Abstract
A method of performing a multiplication operation in the optical domain using a device () comprising: an optical waveguide (), and a modulating element () that is optically coupled to the optical waveguide (), the modulating element () modifying a transmission, reflection or absorption characteristic of the waveguide () dependant on its state, wherein the state of the modulating element () is adjustable by a write signal (). The method comprises: encoding a first value to the write signal (), using the write signal () to map the first value to a state of the modulating element (); encoding a second value to a read signal (); producing an output signal intensity as the transmitted or reflected read signal, wherein the product of the first value and the second value is encoded in the output signal intensity.
