摘要
A novel multichannel dispersion compensator based on a strongly chirped sampled Bragg grating with phase shifts is demonstrated experimentally. With a single phase mask, various channel spacings and dispersion can be achieved by proper control of the sampling period and the phase shifts. A 100 GHz channel-spacing compensator with a dispersion of -1000 ps/nm and another 200 GHz channel-spacing compensator with a dispersion of -500 ps/nm are designed. As an example, a 40 channel, 100 GHz channel-spacing compensator with a dispersion of similar to-560 ps/nm is fabricated. All the designs are based on one phase mask, thus showing the flexibility of our method. (c) 2006 Optical Society of America.
