Abstract

We propose a novel optical channel-selective filter whose center wavelength and bandwidth can be fully controlled. The Proposed filter consists of three identical chirped fiber Bragg gratings (CFBG’s) with fiber stretchers which is to control the reflection spectra of the CFBG’s. We experimentally demonstrate that the proposed tunable filter can select arbitrary channels from a WDM signal.

본 논문에서는 중심파장과 대역폭을 자유롭게 조절할 수 있는 새로운 구조의 광 채널-선택형 필터를 제안하였다. 제안된 필터는 첩 광섬유 격자의 반사 스펙트럼을 조절하기 위해 사용되는 광섬유 신장기를 부착한 동일한 세 개의 첩 광섬유 격자를 사용하여 구성하였다 파장 다중화된 입력신호 중에서 임의의 채널을 선택할 수 있는 제안된 필터의 특성을 실험적으로 보였다.
