Optical Device Technology for Next-generation Computing Using Light.

The performance of conventional computers, which have supported the infrastructure of our digital society and developed in accordance with Moore's law, seems to be approaching its limits. To solve many social issues and achieve a safe, secure, and prosperous society, next-generation computers with performance far beyond that of conventional computers, such as quantum computers, are expected. This article outlines the possibilities of next-generation computers that compute using light and optical device technologies introduced in the Feature Articles of this issue. [ABSTRACT FROM AUTHOR]
