Compact Integrated DBR Laser Source for Absorption Lidar Instruments, Phase I

Metadata Updated: July 17, 2020

We propose to demonstrate a compact integrated laser module that addresses the requirements of the laser source in a water vapor differential absorption lidar (DIAL) system at the 935nm absorption wavelength. Our approach, with the development of the high performance DBR laser diode and the engineering of compact integration technology, will provide narrow linewidth and high power laser modules for numerous Lidar applications with the advantages of reduced size, weight and power (SWaP).

Under this Phase I SBIR we propose to design and fabrication the EPI material and the DBR lasers with a high gain compressive-strained single quantum well (QW) structure, based on Photodigm's proprietary single growth epi, precision gain ridges, and monolithic grating process. We would develop an integrated module that is optically isolated and fiber coupled by investigating the custom build optical isolators of the operating wavelength and designing a compact, hermetic package to achieve high reliability and manufacturability.

Continuing device engineering such as extended mode hop mounting, micro lens beam shaping and package space qualification are expected to be incorporated with this device family under Phase II of this SBIR program.
