Optical module structure

Abstract

The invention discloses an optical module structure. The optical module structure comprises a first optical element, a second optical element and a prism. The prism is a lens with a triangular or trapezoid cross section and is positioned below an optical action part of the first optical element. The prism is provided with a first side surface, a second side surface and a total internal reflection inclined plane, wherein a first spherical raised part is also formed on the first side surface, and a second spherical raised part is also formed on the second side surface. Lights which are sent from the first optical element are emitted into the prism through the first spherical raised part to form parallel lights, are turned for 90 degrees through the total internal reflection inclined plane, are emitted from the prism through the second spherical raised part to form focus convergent lights and are received by the second optical element. The prism can turn the lights of the optical elements, and the spherical raised parts of the prism can appropriately correct the divergence angels of the lights.

Description

technical field [0001] The invention relates to an optical module structure, in particular to an optical module structure for correcting the divergence angle of light and turning the light through a prism with a spherical convex portion on the surface. Background technique [0002] Early telecommunication transmissions (such as networks) were transmitted by radio signals. However, radio signals are prone to attenuation and interference during transmission, and there are also problems such as numerous contacts and easy disconnection. In recent years, due to the development of optical fiber technology and the advantages of anti-interference and attenuation of light wave signals, the transmission of light wave signals instead of electrical signals has become the driving force of signal transmission. [0003] Furthermore, in traditional semiconductors, electrical signals are mostly used to operate. However, due to the above-mentioned innate advantages of optical signals compared...

Problems solved by technology

[0005] However, the outer inclined surface of the microreflector needs to be plated with gold (Au) or aluminum (Al) in addition to extremely high flatness (the general precision is required to be calibrated at 1 / 6 of the wavelength) in manufacture. Highly reflective metal, so it is more troublesome to make

Furthermore, the light emitted by the laser emitting component also has a certain divergence angle, resulting in a low optical coupling efficiency of the light received by the light receiving component. These are issues that need to be considered together
