Description

technical field [0001] The invention relates to a diode, in particular to a microwave diode based on nonlinear electromagnetic induction transparency phenomenon. Background technique [0002] All-optical diode (All-optical diode) is a kind of space nonreciprocal two-port (nonreciprocal) wave transmission device, which has unidirectional conductivity similar to electronic diodes, and can realize unidirectional transmission of optical signals, that is, only light is allowed propagate in one direction. An ideal all-optical diode requires that when light is incident from a certain port, the transmittance can reach 100%, while the light incident from another port has zero transmittance. All-optical diodes have many key applications in the field of optical information, such as optical isolation, all-optical gates, and so on. [0003] Conventional all-optical diodes usually consist of a single local resonant structure. The all-optical diode constructed with a single local resona...
