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

Embodiment 1

[0020] Such as figure 1 Shown:

[0021] Install the cleaned input single fiber 1 and planar waveguide chip 2 together with the fixtures on the six-dimensional adjustment frame in turn, and after finding the two side lines of the input single fiber 1 and planar waveguide chip 2 with the help of the microscopic observation system, first adjust the X axis to be parallel, and then Adjust the two sides on the Y axis to be parallel.

[0022] Turn on the light source, align the infrared light with the input single fiber 1 and the end face of the planar waveguide chip 2, hereinafter referred to as the coupling point, adjust the two light points refracted from the two ends by adjusting the knob, and then adjust the output end of the chip on the right side Place a mirror at the position, observe the corresponding channel light spot reflected by the channel at the output end of the chip, and find the brightest light spot by adjusting the coarse adjustment of the X and Y axes.

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.
