Award Details

Today’s digital society has been supported by electrical circuits made of complementary metal oxide semiconductor (CMOS). However, as circuits become smaller, processing delays increase, which is a major problem. To solve this problem, there is an effort to introduce optical signal processing in electrical circuits. This approach is expected to improve processing delay as the size of the circuits become smaller, since the processing is completed as light signal propagates through the circuit. Based on the background, the author has been engaged in research on optical likelihood calculations and has succeeded in realizing its operation. This research applies the calculation technology to logic circuit. In particular, the author approaches the input-output relationship of the circuit as likelihood calculation. This will enable optics and electrons to share processing in a suitable manner and is expected to open the way to lower latency digital technology.
