This 1.6Tb/s silicon photonic chip adopts the semiconductor technology to integrated optical couplers, splitters, modulators, and 4x16 AWG optical multiplexer into a 5mm x 5mm area. Thanks to the support of Ministry of Science and Technology (MOST) and Taiwan Semiconductor Research Institute (TSRI), this novel 1.6Tb/s silicon photonics chip is designed at the end of 2018 and send to IMEC to produce. After getting the chip at the beginning of 2020, those separate devices of optical edge coupler, optical splitter, optical modulator, and 4x16 AWG optical multiplexer have been measured and verified. The overall chip performance has also been checked by injecting lasers and the light signal has been coupled by singlemode fiber to demonstrate the feasibility of this novel silicon photonics chip.
