Description

technical field [0001] The invention relates to an optical coupling packaging technology of an optoelectronic device, in particular to a novel lateral coupling optical fiber component and a processing method of a semiconductor optoelectronic device in the field of optical communication. Background technique [0002] In optoelectronic devices used to transmit or receive optical signals or energy, many light transmissions between optoelectronic devices and the outside world need to be completed through optical fibers. This problem is called fiber-coupled packaging of optoelectronic devices. [0003] see figure 1 As shown, it is a schematic diagram of a side-coupling optical fiber component in the prior art; that is, the input and output of the light beam at the end face of the optical fiber are not carried out along the axial direction of the optical fiber, but along the radial direction perpendicular to the axial direction . This lateral coupling is realized by processing ...

AI Technical Summary

Problems solved by technology

Since the positioning and fixing of the optical fiber in the prior art is carried out through the through hole on the packaging tube, all fiber coupling processes must be completed with the help of the packaging tube, which makes the optical fiber located on the photoelectric conversion element with the working surface facing down. The coupling method below is difficult to implement because the fiber end face is not visible

Therefore, the existing optical coupling technology limits the application of component flip-chip technology in many optoelectronic devices.
