초록
본 논문에서는 Self-Seeding 방식의 F-P LD를 이용하여 WDM-PON에서의 새로운 파장 가변 광원 구조에 대하여 제안한다. 제안된 광원은 매우 간단한 구조를 갖고도 약 20 nm 정도의 큰 파장 대역을 갖는 장점을 가졌다. 상대적 잡음 밀도(RIN)은 약 -124dB/Hz로 나타났으며, 외부 변조기를 통해 외부 변조한 결과 10Gb/s 신호에 대한 변조 가능성을 확인 할 수 있었다.
A new wavelength tunable laser source based on a self-seeded F-P LD for a WDM-PON system has been proposed in this paper. The proposed laser source has a merit of the wavelength tunable range of approximately 20 nm with very simple setup. The measured minimum relative intensity noise(RIN) was approximately -124 dB/Hz and the possibility of 10 Gb/s external modulation was showed.
