Integrated Planar Lightwave Circuits for UV Generation and Phase Modulation
Project Description
This SBIR Phase I effort proposes to establish the feasibility of developing a UV Planar Lightwave Circuit (PLC); a compact, highly efficient, waveguide-based frequency conversion module for the generation of phase modulated UV radiation for use in multi-wavelength lidar applications such as NASA LaRC's HSRL program. The proposed module will provide phase modulated 355 nm radiation for calibration and stabilization of HSRL's UV interferometric filter, a component required for the accurate measurement of critical aerosol microphysical properties. The goal of the Phase II effort will be the optimization and integration of a compact, monolithic, fiber coupled UV PLC into the next generation HSLR seed laser system. The PLC concept advances NASA's state-of-the-art lidar systems due to its compact, efficient, and reliable design, thus enabling use on small aircraft and space based platforms.

Anticipated Benefits
In addition to NASA's use in various lidar systems, the PLC technology, in general, will find use in fiber and free-space communications where rapid, moderate power phase modulation is required. This technology can also be applied for systems used for environmental and pollution monitoring, spectroscopic measurement techniques, visible display applications, and for stabilizing laser sources and interferometric filters.
The primary customer is NASA Langley's High Spectral Resolution Lidar (HSRL) program for aerosol and cloud characterization. HSRL is targeted for the ACE Mission by NASA's ACE Science Working Group because of the higher information content it provides over backscatter lidar on key aerosol optical and microphysical properties. The proposed UV technology will find uses in other NASA lidar remote sensing programs, such as UV DIAL lidar and Doppler lidar for 3D Winds where compact, low cost, UV stabilized sources are required. This technology also has potential application as a calibration source for visible to UV spectrometers (such as MODIS), as well as for multi-wavelength imaging for atmospheric correction. More »
