Abstract :
The paper presents a monolithically integrated tunable laser with loop-back external cavity tunable based on double ring resonators. It consists of a gain chip and a double ring resonator structure in a loop-back external cavity, made of silicon photonic waveguides. In the experiment, it measures 40-nm wavelength tuning, > 40 dB side mode suppression ratio (SMSR) and the average output power is approximately -3 dBm.
