optical module

Abstract

The invention discloses an optical module, comprising a polyhedron unit, the polyhedron unit transmits the received light beam to a total internal reflection interface after being collimated; the total internal reflection interface is used for total internal reflection of the transmitted light beam to propagating to the catadioptric interface; the catadioptric interface is used to reflect and refract the transmitted total internal reflection beam respectively, the reflected beam propagates to the first refraction adjustment interface, and then propagates to the total external reflection interface, the total The external reflection interface totally externally reflects the reflected light beam to the optical detector; the refracted light beam propagates to the second refraction adjustment interface through the medium outside the polyhedron unit; the second refraction adjustment interface will propagate to the refraction The light beam is focused for propagation to the optical fiber. Since the polyhedral unit is integrally formed by using the same polymer material, the forming molds can be greatly reduced, and the manufacturing cost and complexity are reduced.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to an optical module. Background technique [0002] In the existing optical modules used in the field of optical communication, in order to change the direction of the beam emitted by the laser and then couple it into the optical fiber, or to change the direction of the received light beam in the fiber and then couple it into the optical detector, multiple reflectors arranged at an angle are usually used. mirrors to change the direction of beam transmission. However, the combination of multiple reflectors has many devices, complicated arrangement structure, cumbersome assembly, and the normal transmission of optical signals is easily affected by positional errors. Contents of the invention [0003] In view of this, the present invention proposes an optical module with a novel structure to solve the above technical problems. [0004] In order to achieve the ab...
