An optical switch and an optical transmission method through the optical switch

Abstract

The embodiment of the present application discloses an optical switch and an optical transmission method, which can meet greater network switching requirements. The optical switch in the embodiment of the present application includes: a first fiber collimator, a second fiber collimator, a first refraction structure, a first reflection structure, a second refraction structure, and a second reflection structure, and the first reflection structure includes N The first reflective element, the second reflective structure includes M second reflective elements; the first optical fiber collimator is used to guide the input optical signal to the first refraction structure; the first refraction structure is used to guide the input optical signal from the first optical fiber collimator The optical signal is refracted to the first reflective structure, and the optical signal reflected by the first reflective structure is refracted to the second refraction structure; the second refraction structure is used to refract the optical signal from the first refraction structure to the second reflective structure, and The light signal reflected by the second reflection structure is refracted to the second fiber collimator; the second fiber collimator is used to output the light signal from the second refraction structure.

Description

technical field [0001] The present application relates to the field of optical communication, and in particular to an optical switch and an optical transmission method through the optical switch. Background technique [0002] From the current trend of information technology development, the construction of large-capacity high-speed integrated network and data center has become an inevitable trend of information technology development. As the complexity of the optical network of the metropolitan area network continues to increase, there are often a large number of wavelength division multiplexed (wavelength division multi-plex, WDM) optical signals from different directions at the backbone node of the metropolitan area network. in different directions. [0003] Optical cross-connect (optical cross connect, OXC) components are key components that constitute large-capacity optical networks and data center networks. Among them, the use of three-dimensional microelectromechanica...

Problems solved by technology

[0004] Usually the maximum rotatable angle of each mirror on the mirror array is the same, but limited by the technological level, driving principle and other conditions, it is difficult to increase the maximum rotation capability of each mirror, resulting in the current 3D-MEMS It is difficult for optical switches to meet the ever-increasing demand for network switching
