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.

Abstract

The invention relates to a novel sideward coupling optical fiber component which comprises a first baseplate, an optical fiber and a second baseplate, wherein one surface of the first baseplate is provided with at least one groove; the optical fiber is arranged in the groove; the second baseplate is arranged on the first baseplate and covers the optical fiber; one end of the optical fiber, which is arranged between the first baseplate and the second baseplate, is provided with a bevel, and the bevel is used for performing perfect reflection of beam transmitted in the optical fiber.

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 ...
