Abstract :
We propose a novel optical configuration for a channelized tunable optical dispersion compensator (TODC) with channel-by-channel operation across entire the L-band. The TODC consists of a cyclic frequency arrayed-waveguide grating (AWG) whose free spectral range (FSR) coincides with the channel spacing, a bulk grating and a liquid crystal on silicon. We achieved channel-by-channel compensation over 50 channels with a maximum chromatic dispersion of 800 ps/nm.
