Problems solved by technology

Its working principle is to determine the coupling curing position by searching the maximum value of optical power by the automatic search software during the coupling process. There are some problems in this process method: first, an automatic coupling system is expensive, which is about 10 times that of a manual coupli

Abstract

The invention relates to a planar lightwave circuit splitter, in particular to a technique for coupling a planar lightwave circuit splitter chip and fiber array and provides a low-insertion-loss coupling technique. The low-insertion-loss coupling technique comprises an input single fiber (1), the planar lightwave circuit splitter chip (2) and an output optical fiber array (3). The low-insertion-loss coupling technique is characterized in that the input single fiber (1), the planar lightwave circuit splitter chip (2) and the output optical fiber array (3) are integrated. Difference between a chip insertion loss standard value and a finished product insertion loss value is reduced to the largest extent, phenomena of large loss and unstable performance of an automatic monitoring system caused by errors are avoided, and simultaneously production cost is reduced.

Description

technical field [0001] The invention relates to a planar waveguide optical splitter, in particular to a process method for optical coupling between a planar waveguide optical splitter chip and an FA. Background technique [0002] The main function of the planar waveguide optical splitter is that the optical signal enters from the input end of the device, and after the optical power is evenly distributed through the planar waveguide chip, the output end transmits the evenly distributed optical power to the port that needs to be connected. With the widespread use of planar optical waveguide technology, planar waveguide optical splitters have broad application prospects as the core device of fiber-to-the-home networks. In order to ensure excellent and reliable product performance, we propose a low-cost coupling process optimization scheme. [0003] At present, the most mature coupling technology adopts the imported high-precision automatic adjustment system to realize the align...
