Paper Abstract

We review our recent efforts of optical modulators and routers for photonic networks-on-chip. Through the optimization of the doping concentration and profile as well as the coplanar waveguide electrodes, we demonstrate a 2-mm-long carrier-depletion optical modulator which can work at a speed of 40 Gb/s under a differential voltage of 0.36 V with no reverse bias. We demonstrate a spatially non-blocking five-port optical router based on thermo-optically tuned microring resonators. The optical router has a footprint of 440×660 μm2, a 3-dB bandwidth of 0.31 nm (38 GHz), an extinction ratio of 21 dB for through port, and an extinction ratio of 16 dB for drop port at 1551 nm. 12.5 Gbps high-speed data transmission experiments verify the good routing functionality of the optical router.
