Abstract

We demonstrate generation of linear frequency chirps exhibiting an excursion of 50 GHz (λ₀=1548nm) using an optoelectronic phase-locked loop and integrated silicon photonics interferometer (FSR=3.0GHz), demonstrating the feasibility of an integrated chip-scale frequency-modulated continuous-wave LADAR source.
