Optical transmission system and manufacture method

Abstract

The present invention relates to an optical transmission system and associated manufacturing method. The method includes steps of: forming a first optical waveguide structure, a first coupling site and a second coupling site on a printed circuit board wherein the first optical waveguide structure is mounted between the first coupling site and the second coupling site; mounting a transmitter module having a second optical waveguide structure and a first reflector on the first coupling site to allow the second optical waveguide structure correspond to a first end of the first optical waveguide structure; mounting a receiver module having a third optical waveguide structure and a second reflector on the second coupling site to allow the third optical waveguide structure correspond to a second end of the first optical waveguide structure; and electrically connecting the printed circuit board to the transmitter module and the receiver module by wiring to provide the optical transmission system.

Description

technical field [0001] The present invention relates to an optical transmission system and its preparation method, and especially relates to the combination of semiconductor manufacturing process and the use of related transmitter modules and receiver modules for assembly applications, so that the corresponding optical path layer in the completed printed circuit board An optical transmission system capable of effectively completing optical signal transmission without forming any reflective surface with an inclined angle and a preparation method thereof are designed. Background technique [0002] Traditionally, metal materials are used as lines to provide electrical signal transmission or inter-unit connection, which is quite common in the prior art. In the high-performance electronic system of digital communication, not only more and more processors are installed, but also the speed of signal processing is getting faster and faster, so the quality and speed of signal or info...

Problems solved by technology

However, as far as the current technology is concerned, for printed circuit boards designed with photonic component layers or optical path layers, no matter how the optical waveguide structure is completed inside the optical path layer, for example, it can be made of polymer The (polymer) material forms an optical waveguide structure outside and grinds out the corresponding slope before assembling it into the circuit board, or directly cuts the polymer material on the circuit board with a slope to form a reflective surface with a corresponding slope angle. is a rather difficult process
