Abstract

The invention provides a low-power-consumption all-optical diode based on silicon-based MEMS micro-rings. The low-power-consumption all-optical diode comprises a silicon-based platform, a first micro-ring, a second micro-ring, a first waveguide and a second waveguide. The first waveguide is provided with a first port, and the second waveguide is provided with a second port. Two symmetrical grooveswith the same size are formed in the middle of the silicon-based platform; the two micro-rings have the same radius and are partially suspended beside the grooves, and different coupling efficienciesare realized through different distances between the micro-rings and the waveguide. In the all-optical diode, forward and reverse nonreciprocal transmission of an optical signal can be realized by utilizing a photodynamic effect in the MEMS micro-rings, and tuning of the MEMS micro-rings can be realized by inputting corresponding resonant optical power. The all-optical diode has the advantages ofbeing high in isolation degree and compact in size, being capable of achieving all-optical tuning, and having high application values in the fields of lasers, optical fiber communication systems andthe like.

Description

technical field [0001] The invention relates to the fields of optical communication and integrated optical devices, in particular to a low-power all-optical diode based on a silicon-based MEMS (micro-electromechanical system) microring. Background technique [0002] As a carrier with large communication width and fast information processing speed, optical information carrier is becoming the mainstream direction in the field of communication. An all-optical diode is an optical diode similar to a semiconductor PN junction in electricity. It is a very important device in an integrated optical system, which can realize the non-reciprocal transmission of light, that is, the one-way transmission of light. [0003] In order to realize this non-reciprocal optical device, researchers at home and abroad have proposed many methods, and optical isolators are a common solution. At present, there are three main methods to implement on-chip optical isolators based on silicon-based microri...
