초록

본 논문에서는 엄밀한 수학 없이 상호 주임 잠김에 대한 정성적 이해를 시도하였고, 제안하는 상호 주입 잠김 광원에 대해 분석한다. 또한 두 개의 unpolarized Fabry-Perot Laser Diode (F-P LD)를 이용한 상호 주입 잠김 기반의 Wavelength Division Multiplexing - Passive Optical Network (WDM-PON)용 저가격 광원을 구현하였다. 한 쪽 F-P LD의 파장 변화에 대한 RIN (Relative Intensity Noise) 특성을 측정하였는데, 가변 파장의 범위가 2.07 nm일 때 최소 -110 dB/Hz의 RIN을 보여주었다.

In this paper, we attempted a qualitative understanding of mutual injection locking without rigorous mathematics, and analyzed the proposed mutual injection locked light source. Also, a low-cost WDM-PON light source based on mutual injection locking using two unpolarized Fabry-Perot Laser Diodes (F-P LDs), was implemented. The RIN (Relative Intensity Noise) characteristic for the wavelength change of the F-P LD was measured, and when the variable wavelength range was 2.07 nm, it showed a RIN of at least -110 dB/Hz.
