Embodiment Construction

[0033] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0034] In the current optical communication network, it is necessary to realize the functions of optical path and optical drop at network nodes, and therefore, an optical switch is required. The principle of the currently commonly used optical switch is to drive the liquid through a microfluidic switch, change the position of the liquid in the waveguide, and realize the transmission and total reflection of light, thereby realizing the passage and exit of light. For example, refer to figure 2 , under the action of an external force, the...

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...
