Abstract (in Japanese) (See Japanese page) 
(in English) With a rapid progress of the integrated nanophotonics technology, optical neural networks
based on the integrated nanophotonics attract significant attention. This paper presents an optical neural network architecture which can perform inference processing at a speed of light. The architecture fully exploits optical parallelism of lights using wavelength division
multiplexing (WDM) in vector-matrix multiplication. The paper also presents a light-speed activation circuit based on nanophotonic O-E-O converter. Finally, using an intrusion detection system as an application, the paper explores appropriate circuit structures which can fully exploit ultra-low latency nature and optical parallelism of lights without degrading the inference accuracy.
