Prism, use method of prism, prism set and light assembly

Abstract

The invention relates to the technical field of optical communication, in particular to a prism, the use method of the prism used as a beam adjuster, a prism set and a light assembly. The prism comprises a top surface, a bottom surface, a first side surface, a second side surface, a third side surface and a fourth side surface, wherein the first side surface is divided into a first incident surface and a second incident surface, light beams are incident from first incident surface of the prism and are emitted out from the bottom surface of the prism, the included angle between the incidence direction of the light beams and the emergent direction is 90 degrees, and the horizontal coordinate of the emergent position of the light beams is equal to the horizontal coordinate of the incident position. The light beams are incident from the second incident surface of the prism and are emitted from the bottom surface of the prism, the included angle between the incidence direction of the lightbeams and the emergent direction is 90 degrees, and the translate distance of the horizontal coordinate of the emergent position of the light beams towards the first incident surface relative to the horizontal coordinate of the incident position is the length of the bottom edge of the first side surface. According to the prism, two paths of light can be simultaneously subjected to emergent position and direction adjustment. The light path adjustment is concentrated on one element, the assembly difficulty is reduced, and the material cost is also saved.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a prism, a method for using the prism as a beam adjuster, a prism group and an optical component. Background technique [0002] In the field of optical communication, in order to continuously increase the transmission rate of a single module in its limited volume, one of the main ways is to increase the number of channels of a single module. At the same time, due to the increasing demand for high-speed optical modules, data centers and communication operators hope that the price of high-speed optical modules should be as low as possible to facilitate mass purchases. It is more and more important to improve the internal integration of the module and reduce the cost of the module. [0003] With the wavelength division multiplexing and demultiplexing devices widely used in current modules, it is difficult to make the channel spacing less than 750um. However, for LD (...
