Optical module and optical transmit-receive module

Abstract

The invention discloses an optical module and an optical transmit-receive module; the optical module comprises a first light guide element, an optical element, a first fiber and a light split element; the first light guide element comprises a first surface and a second surface; the optical element is positioned on the first surface; the first fiber abuts against the second surface; the light split element attaches to the first surface so as to partially reflect and transmit a light beam transmitted to the light split element; a refractive index of the light split element is different from that of the first light guide element. In the prior art, the light is difficult to be coupled to the fiber, and partial light is lost in a light coupling process; the optical module can solve the problem.

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...

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
