Silicon Nanophotonic Devices for On-chip Optical Modulation and Switching

A review is given on our recent progresses in silicon nanophotonic devices for optical modulation and switching, which are key elements in a photonic networks-on-chip. High-speed on-chip optical modulation is the key to generate high-bit-rate optical signal for high-capacity optical interconnects, while optical switching is vital for realizing reconfigurable photonic systems. Here we give a review for high-speed LiNbO
