Photonics: Better Optical Fibre Networks

IME researchers have developed a new passive optical network (PON) configuration and a novel silicon photonic transceiver architecture for optical network unit (ONU). The new configuration enables significant reduction of the ONU transceiver size, integration of functions on a silicon chip and requires only one centralized light source. This work demonstrates the feasibility of mass manufacturing monolithic silicon ONU transceivers using low cost CMOS processes, thus speeding up silicon photonics for practical network deployment.
