50x50 Silicon Photonic MEMS Switch with Microsecond Response Time [BPN751]
We developed a new architecture suitable for building a large-scale optical switch with fast response time. We have demonstrated switches with scale of 50x50 and speed of 2.5us 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 50x50 switch on an area less than 1cm x 1cm. We believe that our switch architecture can be scaled-up to larger than 200x200, and beyond.
