Problems solved by technology

To deal with the design of different networks, the return loss of the optical splitter requires different values, but the return loss of the existing optical splitter is fixed, and it is impossible to customize and adjust the return loss value accurately, and it is also impossible to adjust the return loss of a single branches to adjust
Therefore, the current existing technology requires that the return loss is lower than a certain range, and there is no clear requirement for the specific value of the return loss.

Embodiment Construction

[0018] The present invention will be further described below in conjunction with accompanying drawing.

[0019] see figure 1 , the planar optical waveguide optical splitter with customizable return loss of the present invention includes a main waveguide 1 and each waveguide branch 2 extending from the main waveguide 1, the main waveguide 1 and / or at least one waveguide branch 2 is divided into multi-section waveguides by at least one inclined structure 3 . The inclined structure 3 is composed of waveguides at both ends and a middle section. figure 1 Among them, an inclined structure 3 is added on a waveguide branch 2. specifically,

[0020] The present invention increases the section and introduces the change of the refractive index, and the light wave will be reflected at the interface, which is the basic principle of the present application. According to the normal incidence reflection formula, such as figure 2 Situation when middle inclined structure 3 is vertical.

Abstract

The invention discloses a return loss-customizable planar optical waveguide type optical splitter. The return loss-customizable planar optical waveguide type optical splitter comprises a waveguide main path and waveguide branches extending outwards from the waveguide main path; and the waveguide main path and / or at least one waveguide branch is divided into a plurality of sections of waveguides through at least one inclined structure. The return loss of any channel of the optical splitter can be changed, and the return loss of the optical splitter can be customized.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a customized planar optical waveguide optical splitter with adjustable return loss. Background technique [0002] Due to its compact structure, easy integration, excellent performance, and high reliability, the planar optical waveguide optical splitter has become an important device for optical splitting and combining in optical communication systems. The optical splitter can distribute the optical energy to different branches, and can also couple the energy of each branch back to the main circuit. With the application and promotion of the optical splitter network, the demand for optical splitters is also emerging in an endless stream. In order to detect the network system, the return loss customization requirement of the optical splitter is put forward. To deal with the design of different networks, the return loss of the optical splitter requires different value...
