Abstract

The invention relates to a passive coupling method and device. The method includes adding a light source on a first photoelectric array, acquiring the light spot center of the first photoelectric array, acquiring the image center of a second photoelectric array, adjusting the positions of the first photoelectric array and the second photoelectric array and connecting the first photoelectric array and the second photoelectric array in a butting mode and fixing the first photoelectric array and the second photoelectric array when the light spot center of the first photoelectric array and the image center of the second photoelectric array coincide.

Description

technical field [0001] The invention relates to the technical field of photoelectric device production, in particular to a passive coupling method and equipment. Background technique [0002] Manufacturers in the industry basically use passive coupling methods to produce optical modules for multimode optical fiber systems. The current passive coupling method is: obtain the image centers of the two photoelectric arrays, adjust the positions of the two photoelectric arrays so that the image centers of the two photoelectric arrays overlap, and then join the two photoelectric arrays and fix them. [0003] Using the existing passive coupling method will have the following two problems: 1) If the focal point of the photoelectric array deviates from the geometric center, a large ratio of coupling failure will occur; 2) If the optical path is not perpendicular to the surface of the photoelectric array , the coupling cannot be performed. Contents of the invention [0004] In view...
