Embodiment Construction

[0052] In order to facilitate the understanding of the present invention, each term mentioned in the present invention will be described below first.

[0053] Liquid Crystal (English: Liquid Crystal, abbreviation: LC): When the first condition is met (for example, the input voltage is within the first preset range), the liquid crystal can change the incident left-handed polarized light into right-handed polarized light and output it, and convert the incident The right-handed polarized light is changed to left-handed polarized light and exits; when the second condition is satisfied (for example, the input voltage is within the second preset range), the liquid crystal does not change the polarization state of the incident light, and directly transmits the incident light.

[0054] Polymer Polarization Grating (English: Polymer Polarization Grating, abbreviation: PPG): such as figure 2 As shown, if the beam incident on the PPG is left-handed polarized light, the beam is adjusted ...

Abstract

An embodiment of the invention discloses an optical cross-connect device. An embodiment of the invention is characterized in that the optical cross-connect device comprises x input ports, y output ports, a first switch matrix, a second switch matrix and a control device, wherein y is larger than or equal with x. The first switch matrix comprises x*m switches which are arranged in a matrix manner,wherein the x switches in the first row are respectively used for receiving polarized light beams from x input ports. The second switch matrix comprises y*n switches which are arranged in a matrix manner, wherein the y output ports are respectively used for receiving light beams from y switches in a last row. The x input ports are provided with corresponding output ports. The control device is used for controlling the switch so that the light beam which is output from a j-th input port comes to a k-th output port in a preset angle through switches in a j-th line in the first switch matrix andswitches in a k-th line in the second switch matrix when a fact that the j-th input port corresponds with the k-th output ports is determined.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an optical cross-connect device. Background technique [0002] An optical cross-connect (English: Optical Cross Connection, abbreviation: OXC) device has at least two input ports and at least two output ports, and is used to control the light received by any input port of the optical cross-connect device at an optical network node. The signal exits one of the output ports in the optical cross-connect device. [0003] Such as figure 1 as shown, figure 1 It is a structural schematic diagram of an embodiment of an optical crossbar switch based on a micro-electromechanical system (full English name: Micro-Electro-Mechanical System, English abbreviation: MEMS) in the prior art, and the structural schematic diagram is a two-dimensional schematic diagram. The optical crossbar switch in the figure includes a mirror matrix, wherein each mirror 106 in the mirror matrix is ​​contro...
