Our group has previously developed a new architecture suitable for building large-scale MEMS-based silicon photonics optical switches with fast response time. Switches with the scale of 240x240 were demonstrated using our new architecture consisting of an in-plane optical crossbar network with MEMS-actuated couplers implemented on a silicon photonics platform. Increasing the integration level up to 1000x1000 switches and beyond can result in a significant overall optical loss. In a new project we are aiming to develop low-loss switch units in order to address the aforementioned issue by replacing the in-plane optical crossbar network with a double layer structure via wafer bonding method.
