Description

We investigate and develop innovative nonlinear optical devices, primarily for frequency conversion into the mid-infrared (2-5 μm) and far-infrared (8-12 μm) spectral regions. Devices may be based on bulk media, or on fiber or waveguide structures to gain the benefits of optical confinement. We are also interested in beamsteering, modulation, and similar devices that exploit nonlinear optical materials and processes. Current projects focus on quasi-phasematched (QPM) materials, specifically orientation-patterned semiconductors, although other QPM materials, innovative birefringently-phasematched crystals, and techniques for enhancing performance in more established materials are also of interest. Experiments address optical characterization of candidate materials, demonstration and performance characterization of nonlinear devices, and performance modeling, with the goal of improving material fabrication processes and device designs to optimize performance. Facilities are available for measuring absorption and scatter, surface quality, and thermo-optical properties; as well as device output power, spectral content, beam quality, and other performance parameters. Lasers operating at a variety of wavelengths are available for use both in material characterization and as pump sources for frequency conversion experiments. We work closely with the hydride vapor phase epitaxy (HVPE) lab on fabrication of experimental and custom patterned semiconductor materials, and have access to sample cutting and polishing equipment, as well as a class 100 clean room.
