Abstract

An external modulation method is proposed and experimentally demonstrated for the generation of linearly chirped light over broadband with narrow linewidth. Our chirped light source is a combination of an optical recirculating frequency shifter loop and an optical frequency linear sweeper. A linearly chirped light over a range of 200 GHz at a chirp rate of $3.6\times {10}^{16}\mathrm{Hz}/\mathrm{s}$ is generated. The instantaneous linewidth of the chirped light is estimated to be less than 50 kHz.
