Optical switch and optical transmission method applying optical switch

Abstract

The embodiment of the invention discloses an optical switch and an optical transmission method which can meet greater network switching requirements. The optical switch comprises a first optical fibercollimator, a second optical fiber collimator, a first refraction structure, a first reflection structure, a second refraction structure and a second reflection structure, wherein the first reflection structure comprises N first reflection elements, and the second reflection structure comprises M second reflection elements; the first optical fiber collimator is used for guiding an input optical signal to the first refraction structure; the first refraction structure is used for refracting the optical signal from the first optical fiber collimator to the first reflection structure and refracting the optical signal reflected by the first reflection structure to the second refraction structure; the second refraction structure is used for refracting the optical signal from the first refraction structure to the second reflection structure and refracting the optical signal reflected by the second reflection structure to the second optical fiber collimator; and the second optical fiber collimator is used for outputting the optical 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
