Multichannel and rate all-optical clock recovery

We report on a new clock recovery scheme utilizing a birefringent fiber resonator and a polarizer that allows for parallel all-optical processing of multiple channels and rates. It is demonstrated for 21 simultaneous channels, 20 carrying data at 10 Gb/s and one at 40 Gb/s. Earlier demonstrations of multichannel operation have reported four recovered channels at only one single rate
