Abstract

The invention discloses an optical module. The optical module comprises a circuit board and a light emitting sub-module electrically connected with the circuit board, wherein the light emitting sub-module comprises an emitting shell, and a laser, a collimating lens, a converging lens and a planar optical waveguide which are arranged in the emitting shell, and the planar optical waveguide comprises an input optical waveguide and an output optical waveguide which are located on the same input and output end face; the input optical waveguide and the input and output end face are both obliquely arranged relative to the light emitting direction of the laser, the collimating lens converts laser beams emitted by the laser into collimated beams, the converging lens converts the collimated beams into converged beams, and the converged beams are refracted into the input optical waveguide through the input and output end face. The input and output end faces of the planar optical waveguide are obliquely arranged so that the influence of light beams reflected by the input and output end faces on the laser is avoided; the input optical waveguide is obliquely arranged, so the light beam is refracted to the input optical waveguide through the oblique input and output end face, an incident light path is matched, and coupling efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of optical fiber communication, and in particular to an optical module. Background technique [0002] With the development of cloud computing, mobile Internet, video and other new business and application models, the development and progress of optical communication technology has become more and more important. In optical communication technology, the optical module is a tool to realize the mutual conversion of photoelectric signals, and it is one of the key components in optical communication equipment. With the development of optical communication technology, the transmission rate of optical modules continues to increase. [0003] With the rapid development of 5G optical communications and data centers, the demand for high-speed optical modules in the market continues to grow. In order to expand bandwidth and increase network capacity, wavelength division multiplexing technology has been widely ...
