Embodiment Construction

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0031] In order to solve the problem that the air gap between the components of the existing liquid crystal-based WSS core chip is large, which makes the volume of the WSS core chip difficult to compress, and the problem of low optical performance due to the fact that pollutants easily enter the chip end face, this paper An embodiment of the inven...

Abstract

The embodiment of the present invention provides a liquid crystal chip and a wavelength selective switch, wherein the liquid crystal chip comprises an attenuation unit and a switching unit array; theattenuation unit and the switching unit array are bonded through glue; the switching unit array is an array composed of a plurality of switching units, wherein the previous switching unit and the later switching unit are bonded through glue; the attenuation unit is used for adjusting the attenuation of an optical signal; and the switching unit is used for adjusting the deflection angle of the optical signal. The liquid crystal chip and the wavelength selective switch provided by the embodiment of the present invention are bonded through the glue to form a liquid crystal chip; the structure iscompact and firm; there is no air gap between components inside the conventional WSS core chip, thereby preventing pollutants from entering the chip end face. In addition, the glue replaces the air gap between the components inside the conventional WSS core chip, thereby improving the refractive index of the gap, effectively reducing the thickness of the liquid crystal chip, and improving the WSSbandwidth index based on the liquid crystal chip.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of optical communication, and in particular to a liquid crystal chip and a wavelength selective switch. Background technique [0002] With the development of WDM systems, people have higher and higher requirements for system flexibility. The wavelength selective switch has the function of arbitrary port wavelength up and down, and its precise optical power attenuation control function. It has become a ROADM (Reconfigurable Optical Add -Drop Multiplexer, a key component of a reconfigurable optical add-drop multiplexer) system, has been widely used in intelligent optical networks. [0003] WSS devices are composed of conventional optical coupling elements (collimators, lenses, gratings, etc.) and core optical chips, where the core optical chip is the key part of WSS devices. At present, there are three mainstream WSS core chip implementation schemes: micro-electromechanical system (Micro...
