Coheerent lightwave associative memory experiment retrieving embedded complex-amplitude signals

摘要

A coherent lightwave neural network system has been constructed for the first time. The novel system deals with phase and amplitude information consistently. Experiments demonstrate that complex-amplitude signal vectors embedded in its neural connections are recalled successfully. The coherent networks are expected to relaize various attractive neural features such as carrier-frequency domain parallelism and self-organization of activeness mechanisms. The reported result can be a milepost toware such future highly functional neural network architecture and hardware.
