Description

technical field [0001] The invention belongs to the technical field of optical communication devices or equipment, and in particular relates to an exclusive OR optical logic gate based on Ag / nonlinear material. Background technique [0002] Optical logic gates are essential components in optical information processing and optical computing. Traditional electrical logic gates are composed of triodes cascaded. For one logic gate, multiple triodes need to be driven, so the power consumption of the device is relatively high, while the optical logic gate is equivalent to a selection switch when working, and the power consumption is relatively low. All the inputs of the optical logic gate are parallel, each input element is independent of each other and the final operation result is expressed in the form of light intensity in the optical domain. As one of the key devices to realize all-optical integrated optical circuits, all-optical logic gates are widely used in the field of mi...
