Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0038] figure 1 Shown is a schematic structural diagram of a traditional 1x16 optical splitter. The main problem is that the distance between the input port and the output port is required to be long, resulting in a long overall length of the optical splitter, which makes it difficult to meet the current high integration requirements of optoelectronic devices. In order to solve the above-mentioned problems existing in the traditional 1x16 optical splitter, the present invention proposes the 1x16 optical splitter of the present invention. The 1x16 optical splitter has small volume and low loss, and ...

Abstract

The invention discloses a 1*16 optical splitter with a special Y-branched type bending structure. The overall length Z of the 1*16 optical splitter is equal to 35,000mum, the spacing Xtheta of every two adjacent output waveguides is equal to 127mum, and both input waveguides and the output waveguides have a rectangular cross section of 6mum*6mum. A traditional 1*16 optical splitter has the problemthat the distance between an input port and an output port is long, so that the overall length of the optical splitter is long, and the requirement for the high integration of existing optoelectronicdevices is difficult to achieve. The 1*16 optical splitter with the special Y-branched type bending structure provided by the invention solves the problem existing in a traditional 1*16 optical splitter; and the 1*16 optical splitter is small in size and low in loss, and meets the requirements for the high integration of the optoelectronic devices.

Description

technical field [0001] The invention relates to a passive optical splitter, in particular to a 1x16 optical splitter with a special Y-branch type curved structure. Background technique [0002] With the increase of users' demand for information and the popularization of digital products, communication networks based on copper cables are gradually being replaced by optical communication networks. The improvement and development of optical communication network depends on the improvement of the performance of active and passive optical devices. Among them, the passive optical splitter is the core optical device connecting the optical line terminal and the optical network unit in the passive optical network. The traditional Y-branch waveguide structure has mode conversion and radiation loss near the branch point, which can be ignored only when the branch angle is small, which makes the splitter very long and the structure of the device is not compact.
