Chromatic dispersion compensation device |
摘要 |
A method and device is disclosed for dispersion compensation of an optical signal having periodic dispersion within a multi-channels system. For example interleaved optical channels often exhibit dispersion having a characteristic that is repeated in adjacent channels. By providing a periodic device in the form of a multi-cavity GT etalon having a free-spectral range that corresponds to the channel spacing the dispersion in the interleaved signal can be lessened and practically obviated or balanced to a desired level. Advantageously, the input and output angle of the signal can be varied to provide fine tuning. This invention provides a device and method to achieve that end.
