Optical communication switch, optical control method, array substrate and display device

Abstract

The invention discloses an optical communication switch, an optical control method, an array substrate and a display device. Specifically, the invention provides the optical communication switch, comprising a first substrate and a second substrate disposed opposite to each other, a first optical medium layer, a second optical medium layer, and a heating device. The first optical medium layer is disposed between the first substrate and the second substrate and is formed of a phase change material which has a first refractive index in the first state and a second refractive index in the second state. The second optical medium layer is disposed between the first substrate and the second substrate and is in contact with the first optical medium layer, and the refractive index of the second optical medium layer matches the first refractive index or the second refractive index. The heating device is configured to enable the phase change material to transition between the first state and thesecond state. Therefore, the optical communication switch has a simple manufacturing process and a fast response time.

Description

technical field [0001] The invention relates to the field of optical devices, in particular to an optical communication switch, a light control method, an array substrate and a display device. Background technique [0002] With the rapid development of science and technology, the capacity of information transmission in the communication field is increasing day by day, and people's requirements for bandwidth are getting higher and higher. How optical communication networks can transmit information efficiently and quickly has become one of the focuses of people's research. In the current optical communication network, in order to increase the transmission bandwidth, optical signals of multiple wavelengths are usually transmitted in an optical fiber, and each optical signal of a wavelength represents a channel, that is, there are multiple channels in an optical fiber at the same time, and multiple data are transmitted. When it is necessary to use a certain part of the data tran...
