Abstract

In this paper, a wavelength tunable light source based on mutually injected locking with two F-P LDs, has been constructed and then analyzed for wavelength shift and RIN (Relative Intensity noise) according to temperature. We have measured maximum about 2 nm for the wavelength shift and minimum -110dB/hz for the RIN. Also, the RIN and beating noise in eye patterns are increased by changing temperature high.

본 논문에서는 두개의 Unpolarized F-P LD를 이용한 상호주입 잠김 기반의 파장 가변 광원을 구현하였고, 온도 변화에 따른 특성을 분석하였다. 온도 변화에 따라 파장의 가변 범위가 최대 약 2nm이고, 상대적 밀도 잡음(RIN)는 최저 -110dB/Hz임을 확인하였다. 또한 온도가 높을수록 상대적 밀도 잡음(RIN)는 높아지고, Eye Pattern에 Beating Noise가 발생하는 것을 알 수 있었다.
