Title:
OPTICAL MODULE
Document Type and Number:
WIPO Patent Application WO/2020/057310
Kind Code:
A1
Abstract:
An optical module, comprising: a circuit board (31), an optical transmission module (32), and an optical detector array (33) provided on the surface of the circuit board (31). Glue (34) is coated on the surface of the optical detector array (33); in one case, a rear end of the optical transmission module (32) is a slope, the glue (34) is in contact with the optical transmission module (32), and light is reflected on the slope of the optical transmission module (32), and is emitted into the surface of the optical detector array (33) by means of the glue (34); in the other case, the rear end of the optical transmission module (32) is the slope, the glue (34) is not in contact with the optical transmission module (32), and light is reflected on the slope, and emitted into the surface of the optical detector array (33) after sequentially passing through air and the glue (34). By coating the glue (34) on the surface of the optical detector array (33), coupling efficiency can be improved and a coupling time duration is shortened by using a simple optical path system, and a position accuracy requirement for devices in the optical path system is reduced.
