As part of a NEDO project, the University of Tokyo, conducting a joint research with the Photonics Electronics Technology Research Association (PETRA), has succeeded in developing a semiconductor optical modulator with the world's highest level of performance, which reduces optical loss by one-tenth and can convert an electric signal to an optical signal with five times greater efficiency compared to conventional modulators. This semiconductor optical modulator has the potential to contribute to significant power savings and the miniaturization of silicon optical integrated circuits which are important to applications that communicate enormous amounts of information at high speed, such as data centers, IoT technologies, and artificial intelligence.
The results were published on July 24, 2017 (GMT) in the online version of the United Kingdom science journal Nature Photonics.
