Problems solved by technology

However, the locking structure is usually complex and requires a very large chip area. Therefore, it is difficult to expand the existing MEMS optical switch to realize an optical switch array with multiple micromirror arrays on one chip, that is, it is difficult to achieve large-scale integration.

Embodiment Construction

[0014] The optical switch and the optical switch array provided by the embodiments of the present invention are described in detail below in conjunction with specific embodiments.

[0015] In order to solve the problems existing in the prior art, the optical switch provided by the embodiment of the present invention adopts the shape self-adaptive reshaping FSR material in its locking structure, and uses the FSR material to switch the light-on state of the optical switch to perform state switching. Locking, because the FSR material has deformation memory and structural remodeling, it can simply realize the state locking of the optical switch, on the one hand, it does not need to occupy a large chip area, on the other hand, it makes the optical switch easy to implement Integration at scale.

[0016] For example, the optical switch may be a MEMS optical switch, which includes a semiconductor substrate with a rotating part and a twist beam, a micro-mirror arranged on the surface o...

Abstract

The embodiment of the invention discloses an optical switch, comprising a semiconductor substrate, a micro-reflector and a first locking structure, wherein the semiconductor substrate comprises a first rotary part and a first torsion beam arranged at two ends of the rotary part, and the first torsion beam is used for driving the first rotary part to rotate; the micro-reflector is arranged on the surface of the first rotary part of the semiconductor substrate; and the first locking structure is arranged on the surface of the first torsion beam and comprising a form self remodelling (FSR) material layer and a hot field source, wherein the hot field source is used for providing a hot field to the FSR material layer, the FSR material layer is used for remodelling forms under the action of thehot field, and therefore, the first rotary part and the micro-reflector are locked at positions after rotating. The embodiment of the invention further discloses an optical switch array.

Description

technical field [0001] The present invention mainly relates to optical communication technology, and in particular, relates to an optical switch and an optical switch array applicable to an optical communication system. Background technique [0002] In traditional communication networks, transmission media can be divided into two types: wired and wireless. Wireless transmission media mainly include microwave lines and geostationary satellite lines, while wired transmission media mainly include copper wire cables and fiber optic cables. After entering the era of digital communication, because the information capacity of copper wire and cable is too small to meet the needs of rapidly developing digital communication, and the information capacity of optical fiber can be several orders of magnitude higher than that of copper wire, therefore, optical communication using optical fiber as the transmission medium Technology has attracted more and more attention from the industry. ...
