LIDAR utilizing SGDBR Lasers

Project Description

students in EE labLIDAR (Light Detection and Ranging) system architectures and applications that are enabled by single-chip wavelength tunable Sampled Grating Distributed Bragg Reflector (SGDBR) lasers are being developed in this project. These new single chip lasers are unique in that wide-wavelength tunability (60 nm at 1550 nm center wavelength), high-speed frequency switching times (5ns), and high-speed amplitude modulation (5 GHz) functions are all integrated on the same semiconductor chip. The goal of this work is to adapt these lasers for applications in LIDAR. The first phase of proposed research is to find LIDAR architectural solutions that utilize the strengths of this laser class and mitigate the weaknesses. Figure1 shows two graduate students taking a break from their LIDAR activities for a photo opportunity.   A short presentation on the topic is at this link.   LIDAR DERICKSON
