Researchers at University of California, Berkeley have developed a novel silicon photonic switch, which is the largest-scale and lowest-energy loss switch reported to date. It features switching time of sub-micro seconds and broad bandwidth of hundreds of nanometers. Measuring 1 x 1 cm, switch has 50 input and 50 output channels, for total of 2,500 switching elements. Researchers will present switching innovation on March 23, 2015 during Optical Fiber Communication Conference and Exposition.
