DOD / NAVY
A novel approach to achieving a high performance narrowline optical source with large output power dynamic range and short pulsewidth is proposed using a silicon platform for ultra low-cost and high reliability. We are using recent breakthroughs in silicon photonics that allow integration of DFB lasers with SOA switches in a low cost platform. Some of the key advantages to our proposed approach include: 1) Low linewidth by using low loss silicon waveguides 2) DFB lasers with an integrated external cavity and electronic feedback for control of both pulse amplitude and phase 3) Large extinction ratio: >80 dB pulses for improved dynamic range. 4) Integration: The key to success of this project is integration of the laser, waveguide and switch and optional phase modulator. This is essential to achieve the low noise figure, high powers, compact size and low cost, by eliminating packaging costs of discrete implementations while retaining the performance.
