Abstract
There is provided an optical signal processing device that constitutes a neural network, characterized by including an optical computation device including: a light modulator that converts an electric signal into an optical signal; an optical circuit that converts the optical signal through computation processing on the optical signal which has been modulated by the light modulator, the optical circuit including an optical medium with a controlled distribution of a refractive index corresponding to a weight in the neural network; and a light receiver that obtains an output signal by receiving the optical signal which has been converted by the optical circuit.
