초록

색 분산과 색 분산 경사를 보상하기 위하여 결합 계수가 파장 축을 따라 첩 된 순 위상 샘플링 광섬유 Bragg 격자를 제안하였다. 기존의 샘플링 주기의 첩과 결합 계수의 첩을 동시에 이용하여 동일한 파장 다중 채널들의 대역폭들을 얻을 수 있었다.

We demonstrated numerically that both the chromatic dispersion and the dispersion slope could be compensated by using purely phase-sampled superstructure fiber Bragg gratings provided with chirp of coupling coefficient along the wavelength axis. Also, we propose a purely phase-sampled Bragg grating for dispersion and dispersion slope compensation by introducing a chirp in coupling coefficient and sampling function. The bandwidth of all reflected channels can be equalized.
