Modulator-based high-speed optical signal processing for optical time-division multiplexing

We present a summary of our recent progress in high-speed optical signal processing for optical time-division multiplexing, based on electro-optic modulators. Optical frequency-comb generation, optical Nyquist pulse generation, equivalent switching window expansion for demultiplexing, and simultaneously clock recovery and demultiplexing are realized by structures with modulators embedded as the key components.
