Abstract We developed a new architecture suitable for building a large-scale optical switch with fast response time. We have demonstrated switches with a scale of 64x64 and speed of sub-microsecond using our new architecture. The switch architecture consists of an optical crossbar network with MEMS-actuated couplers and is implemented on a silicon photonics platform. Thanks to high integration density of the silicon photonics platform, we could integrate 64x64 switch on an area less than 1cm x 1cm. To our knowledge this is the largest monolithic switch, and the largest silicon photonic integrated circuit, reported to date. The passive matrix architecture of our switch is fundamentally more scalable than that of multistage switches. We believe that our switch architecture can be scaled-up to larger than 200x200.
