We realized a wide-passband multi-channel tunable optical dispersion compensator for 88 WDM signals with 50-GHz spacing by combination of an arrayed-waveguide and bulk gratings. It utilizes a novel optics arrangement for high wavelength resolution.
We review a multi-channel tunable optical dispersion compensator (TODC) with channel-by-channel operation that allows us replace a number of conventional TODCs with a single module.
We propose a novel optical configuration for a multichannel tunable optical dispersion compensator (TODC) with channel-by-channel operation across the entire L-band. The TODC consists of a cyclic frequency arrayed-waveguide grating whose free spectral range coincides with the channel spacing, a bulk grating, and a liquid crystal on silicon. We achieved channel-by-channel compensation over 50 channels...
