Research description for a Rutile coupling prism

This description will give a brief insight into our research at the Light Technology Institute of the University of Karlsruhe (TH), Germany. One of our research fields is the development of electrically pumped organic semiconductor thin film lasers. Due to the complex behavior of these lasers numerous electrical and optical characterization is necessary. One of the most important optical properties of these organic semiconductor laser structures is the attenuation coefficient of the multilayer waveguide, which has to be carefully optimized to reduce waveguide losses 1. The first step in the optimization process is the numerical simulation of the anticipated waveguide design. Next, the optimized sample structure is fabricated and characterized in our attenuation measurement setup. This measurement is done as follows:
A Rutile coupling prism is pressed onto the waveguide. A laser beam is then coupled into the prism so that total reflection occurs inside the prism at the interface to the waveguide. In the vicinity of the waveguide the overlapping incident and reflected beam generate a standing wave. The evanescent field of that standing wave penetrates into the waveguide.





Evanescent field coupling



Under a certain angle and if the phase match conditions are fulfilled, the evanescent field stimulates a mode that is guided by the waveguide. The phase match condition can only be achieved when the refractive index of the prism is at least as high as the effective refractive index of the waveguide. Owing to its high refractive index, Rutile is an ideal material for use as a coupling prism in such a prism-coupler waveguide attenuation measurement setup.
 


Beam coupling into waveguide



A small fraction of the guided light is scattered out of the waveguide. The intensity of this scattered light is assumed to be proportional to the intensity of the guided light. Thus the intensity distribution inside the waveguide along the propagation direction can be directly determined through measuring the intensity of the scattered light.




Streak caused by scattering inside the waveguide



The intensity distribution is detected with a computer controlled, cooled CCD-Camera. Finally the attenuation coefficient is extracted from the measured data.




Intensity distribution measured with CCD-Camera




The following two figures show the setup that was used for the measurements.
 




Schematic of the Setup
 



Photography of the Setup



Additionally, it is possible with our setup to measure the refractive index and the thickness of waveguides that support a minimum of two guided modes. These parameters can be extracted from the dependency between coupling angle and effective refractive index.

Nonlinear Optics in Whispering Gallery Mode Resonators

By Irina Novikova, Matt Simons and David Gribbin, the College of William and Mary

The reliable and efficient generation of an electromagnetic field with non-classical statistics, such as "squeezed" light or single-photon wave-packets, is important for a number of applications from reduced measurement uncertainty to new secure quantum information protocols. Nonlinear processes in optical crystals, such as second-harmonic generation and spontaneous parametric down-conversion, are currently the best and the most common ways to produce non-classical light. However, traditional experimental arrangements with bulk nonlinear crystals are rather involved and usually require high-power lasers and high-quality optical cavities.
Our research group explores the potential for using high-Q crystalline whispering gallery mode resonators (WGMRs) to accomplish low-threshold nonlinear frequency conversion. Such cavities support the modes of light traveling along the circumference of a polished disk (or sphere) through total internal reflection (TIR). Because no actual mirror is used, extremely high quality factors can be achieved in WGMR. Theoretically, the lifetime of a photon inside the cavity is limited by the scattering on the impurities. This limit depends on a crystal, but generally the quality factor ranges from 109 in LiNbO3 to over 1013 in CaF2. More realistically, the Q-factor of a microresonator is limited by the quality of surface polishing. The efficient coupling of laser radiation in a WGM in a crystalline disc is possible by means of frustrated total internal reflection in a coupling prism, as shown in Figure 1. If the rim of a disk is close enough to the reflecting surface of the prism, an evanescent wave tunnels across the gap and that light excites one or several WGMs. It is crucial that the index of refraction of the prism is higher than that of the disc, and thereby the optical coupling is achieved at the critical angle. Rutile with its high refractive index makes a perfect material for coupling to most nonlinear crystals.

The quality factor is a measure of the lifetime of energy stored in the cavity - the longer the lifetime, the more energy can build up in the cavity. For a very high-Q cavity even a low input light intensity can turn into a very intense field in the resonator. For example, a WGM cavity with a Q-factor of 1010 will support a photon for a millisecond (10-3 s), and that is significantly higher than the round trip time (typically in nanosecond scale). In our experiments we have achieved the quality factor of 107 as shown in Figure 2.
Significantly higher values will be achieved with improved polishing. This long cavity lifetime combined with small mode volume makes the crystalline WGMR attractive for the quantum optics applications. In particular, we are interested in observing narrow-band low-threshold second-harmonic generation as a first step toward the generation of heralded single photons. Our ultimate goal is to produce high-quality WGM discs that convert a laser light at 795nm to 397nm and vice versa, since 795nm is the wavelength of the D1 spectral line in Rubidium. Such nonclassical light will be organically integrated with the atomic quantum memory and slow light experiments conducted by our group. However, as the first step we are practicing polishing LiNbO3 disks and observing nonlinear conversion of 1064 nm pump laser light into 532nm second harmonic, as shown in Figure 3. Efficient frequency conversion can be achieved since the non-critical phase-matching (i.e. the matching of the refractive indices for the fundamental and doubled optical frequencies) is possible by tuning the temperature of the nonlinear material. The pump and generated fields are orthogonally polarized, and thus the dichroic rutile prism offers additional benefit for separating them, as they couple out of the WGM disc at significantly different angles.

Pismo pulse picker
The Pismo pulse picker systems is as a pulse gating system that lets single pulses or group of subsequent pulses from a femtosecond or picosecond pulse train pass through the system, and stops other radiation. The system is perfectly suitable for most commercial femtosecond oscillators and amplifiers. The system can pick either single pulses, shoot bursts (patterns of single pulses) or pick group of subsequent pulses (wider square-shaped HV pulse modification). HV pulse duration (i.e. gate open time) is 10 ns in the default Pismo 8/1 model, but can be customized from 3 to 1250 ns upon request or made variable. The frequency of the picked pulses starts with single shot to 1 kHz for the basic model, and goes up to 100 kHz for the most advanced one.
The Pockels cell is supplied with a control unit that is capable of synching to the optical pulse train via a built-in photodetector unit, while electric trigger signal is also accepted. Two additional delay channels are available for synching of other equipment to the pulse picker operation. Moreover, USB connectivity and LabView-compatible drivers save a great deal of your time on storing and recalling presets, and setting up some automated experimental setups. One control unit is capable of driving of up to 3 Pockels cells, and this comes handy in complex setups or contrast-improving schemes. The system can also be modified to supply two HV pulses to one Pockels cell unit, making it a 2-channel pulse picker system. This may be essential for injection/ejection purposes when building a regenerative or multipass amplifier system.

AOTF Infrared Spectrometer
Del Mar Photonics offer a handheld infrared spectrometer based on the acousto-optic tunable filter (AOTF). This instrument is about the size and weight of a video camera, and can be battery operated. This unique, patented device is all solid-state with no moving parts. It has been sold for a wide variety of applications such as liquid fuel analysis, pharmaceutical analysis, gas monitoring and plastic analysis. Miniature AOTF infrared spectrometer uses a crystal of tellurium dioxide to scan the wavelength. Light from a light source enters the crystal, and is diffracted into specific wavelengths. These wavelengths are determined by the frequency of the electrical input to the crystal. Since there are no moving parts, the wavelength scanning can be extremely fast. In addition, specific wavelengths can be chosen by software according to the required algorithm, and therefore can be modified without changing the hardware. After the infrared radiation reflects off of the sample, it is converted into an electrical signal by the detector and analyzed by the computer. Del Mar Photonics is looking for international distributors for RAVEN - AOTF IR spectrometer for plastic identification and for variety of scientific and industrial collaborations to explore futher commercial potential of AOTF technology.

Femtosecond Transient Absorption Measurements system Hatteras Hatteras-D femtosecond  transient absorption data acquisition system
Future nanostructures and biological nanosystems will take advantage not only of the small dimensions of the objects but of the specific way of interaction between nano-objects. The interactions of building blocks within these nanosystems will be studied and optimized on the femtosecond time scale - says Sergey Egorov, President and CEO of Del Mar Photonics, Inc. Thus we put a lot of our efforts and resources into the development of new Ultrafast Dynamics Tools such as our Femtosecond Transient Absorption Measurements system Hatteras. Whether you want to create a new photovoltaic system that will efficiently convert photon energy in charge separation, or build a molecular complex that will dump photon energy into local heat to kill cancer cells, or create a new fluorescent probe for FRET microscopy, understanding of internal dynamics on femtosecond time scale is utterly important and requires advanced measurement techniques.

Del Mar Photonics adaptive optics and wavefront sensors: ShaH-0620 wavefront sensor with telescope Wavefront Sensors: ShaH Family
A family of ShaH wavefront sensors represents recent progress of Del Mar Photonics in Shack-Hartmann-based technology. The performance of Shack-Hartmann sensors greatly depends on the quality of the lenslet arrays used. Del Mar Photonics. developed a proprietary process of lenslet manufacturing, ensuring excellent quality of refractive lenslet arrays. The arrays can be AR coated on both sides without interfering with the micro-lens surface accuracy. Another advantage of the ShaH wavefront sensors is a highly optimized processing code. This makes possible real-time processing of the sensor data at the rate exceeding 1000 frames per second with a common PC. Due to utilizing low-level programming of the video GPU, it is possible to output the wavefront data with a resolution up to 512x512 pixels at a 500+ Hz frame rate. This mode is favorable for controlling modern LCOS wavefront correctors.
The family of ShaH wavefront sensors includes several prototype models, starting from low-cost ShaH-0620 suitable for teaching laboratory to a high-end high-speed model, ShaH-03500. The latter utilizes a back-illuminated EM-gain CCD sensor with cooling down to -100癈. This makes it possible to apply such a wavefront sensor in astronomy, remote sensing, etc.

Frequency-stabilized CW single-frequency ring Dye laser DYE-SF-007 pumped by DPSS DMPLH laser installed in the brand new group of Dr. Dajun Wang at the The Chinese University of Hong Kong.
DYE-SF-077 features exceptionally narrow generation line width, which amounts to less than 100 kHz. DYE-SF-077 sets new standard for generation line width of commercial lasers. Prior to this model, the narrowest line-width of commercial dye lasers was as broad as 500 kHz - 1 MHz. It is necessary to note that the 100-kHz line-width is achieved in DYE-SF-077 without the use of an acousto-optical modulator, which, as a rule, complicates the design and introduces additional losses. A specially designed ultra-fast PZT is used for efficient suppression of radiation frequency fluctuations in a broad frequency range. DYE-SF-077 will be used in resaerch of Ultracold polar molecules, Bose-Einstein condensate and quantum degenerate Fermi gas and High resolution spectroscopy
