초록

평판도파로 상에 FP-LD와 샘플격자를 하이브리드 집적하여 듀얼 모드로 발진하는 외부 공진기 레이저를 구현하였다. 샘플격자에 인가되는 전류를 50mA에서 55mA로 변화시킴으로써 듀얼 모드간의 beat 주파수를 132GHz에서 406GHz로 스위칭할 수 있었다.

Abstract

We demonstrate a beat frequency-Switchable dual-mode external cavity laser hybrid integrated on planar lightwave circuit with an FP-LD and a sampled grating as external reflector. The dual-mode external avity laser was able to switch its beat frequency from 132GHz to 406GHz by changing LD current from 50mA to 55mA.
