Advanced Si photonics platform for high-speed and energy-efficient optical transceivers for datacom

A mature silicon photonics platform including various materials for a wide range of functionalities is needed to achieve high-speed and energy-efficient transceivers for Datacom. We present the latest developments of our 200mm silicon photonics platform including new devices in silicon nitride along with active devices. In particular, we demonstrate a high performance SiN Echelle Grating CWDM (de-)multiplexer obtained with advanced photolithography tools, hybrid Si-SiN polarization splitter rotator, SiN edge coupler and low-loss, low-crosstalk Si-SiN and SiN-SiN crossings.
