Abstract
An optical operational element which enables a multilayered optical neural network to be constructed without using an optical amplifier is provided. The optical operational element includes: a photothermal conversion unitwhich converts light energy of input light A into thermal energy; a light intensity variation unitwhich is in contact with the photothermal conversion unitand which varies, in accordance with a temperature variation accompanying heat generation or heat absorption by the photothermal conversion unit, intensity of external light B that is introduced from the outside; and a housing unitwhich houses the light intensity variation unitand which introduces the external light B from one side and outputs output light C obtained by attenuating intensity of the external light B to the outside on an opposite side to the one side.
