Problems solved by technology

[0003] Existing optical fiber communication mainly uses laser diodes packaged in a transistor-shaped can (TO-can) as the light-emitting terminal. However, laser diodes packaged in a transistor-shaped can can only be installed vertically on the circuit board. Difficulty increasing to the optical fiber, and causing some light to be lost during coupling
[0004] In addition, transistor-shaped cans are mostly made of metal materials, and the overall manufacturing cost is high, which makes the laser diode module packaging volume unable to be miniaturized

Abstract

The invention discloses an optical module and an optical transceiver module. The optical module includes a first light guiding element, an optical element, a first optical fiber, and a light splitting element. The first light guiding element includes a first surface and A second surface, the optical element is located on the first surface, the first optical fiber is in contact with the second surface, the light splitting element is attached to the first surface, and is used for partial reflection and partial transmission of light transmitted to the light splitting element For light beams, the refractive index of the light splitting element is different from the refractive index of the first light guiding element. The invention can solve the technical problem that the difficulty of coupling light to the optical fiber in the prior art is increased, and part of the light is lost during coupling.

Description

technical field [0001] The invention relates to an optical module and an optical transceiver module, in particular to an optical module and an optical transceiver module which use total internal reflection to change the transmission path of light beams. Background technique [0002] Optical fiber communication refers to a way of transmitting information by using light and optical fiber. It belongs to a kind of wired communication, which has the advantages of large transmission capacity and good confidentiality, and has gradually become the most important wired communication method today. [0003] Existing optical fiber communication mainly uses laser diodes packaged in a transistor-shaped can (TO-can) as the light-emitting terminal. However, laser diodes packaged in a transistor-shaped can can only be installed vertically on the circuit board. Difficulty in getting to the fiber increases, and some light is lost during coupling. [0004] In addition, the transistor-shaped c...
