[0002] Optical splitter, also known as optical splitter, is one of the important passive components in optical fiber link. Planar optical waveguide splitter is a kind of optical splitter, which has small size, wide working wavelength range and high reliability. , good splitting uniformity, etc., especially suitable for connecting central office and terminal equipment in passive optical networks (EPON, BPON, GPON, etc.) and realizing splitting of optical signals. The existing planar optical waveguide splitter is in the manufacturing process Due to the problems of the process itself, it is easy to cause difficulties in quality control and high defective rate, which not only greatly affects the production efficiency but also brings economic losses to the production and processing enterprises.

Abstract
The invention discloses a method for manufacturing an optical branching device. The method comprises: manufacturing a planar optical-waveguide branching device chip; carrying out coupling of the planar optical-waveguide branching device; encapsulating the planar optical-waveguide branching device; testing the planar optical-waveguide branching device; and packaging the planar optical-waveguide branching device. The manufacturing process is simple and error occurrence is avoided; strict inspection links are set in all processes, so that product quality control is improved, the defective percentage is reduced effectively, and production of lots of inferior-quality products is avoided. Therefore, the production efficiency of the qualified planar optical waveguide branching device is improvedobviously; and economic losses caused by inferior-quality products are avoided for production enterprises.
Description
Technical field [0001] The invention relates to the technical field of manufacturing a planar optical waveguide splitter, in particular to a manufacturing method of an optical splitter. Background technique [0002] Optical splitter, also known as optical splitter, is one of the important passive components in optical fiber links. Planar optical waveguide splitter is a kind of optical splitter, which has small size, wide operating wavelength range and high reliability , Good splitting uniformity, etc., especially suitable for passive optical networks (EPON, BPON, GPON, etc.) to connect central office and terminal equipment and realize optical signal splitting. The existing planar optical waveguide splitter is in the manufacturing process Due to the problem of the process itself, it is easy to cause difficulties in quality control and high defective rate, which not only greatly affects the production efficiency but also brings economic losses to the production and processing enter...
