Raman amplification-based multiwavelength synchronous pulse compressor and its application to all-channel OTDM demultiplexing in a single-parametric-gate

We demonstrate full OTDM demultiplexing in single-parametric-gate using Raman amplification-based multiwavelength pulse compressor. Four WDM synchronous pulses are simultaneously compressed to smaller than 3-ps before multiwavelength demultiplexing. Less than 1.5-dB penalties are obtained with 0.2-dB sensitivity variation among demultiplexed channels.
