Embodiment Construction

[0042]The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0043] The optical fiber of the optoelectronic device proposed by the present invention is accurately aligned and fixed. A transition block is installed in the tube shell. A photoelectric functional unit 130 is installed on the transition block. A transition block assembly 700 is installed on the side of the tail tube inside the tube shell 110. The part of the 125 μm bare optical fiber 310 of the assembly 500 close to the photoelectric functional unit 130 is fixed on the transition block assembly 700 with glass solder 910, the bare optical fiber 310 of the optical fiber assembly 500 is welded together with the optical fiber metal tube 520 with the low-temperature glass solder 510, an...

Abstract

The invention provides an accurate alignment fixing structure and an alignment fixing method of optic fiber of a photoelectron device. The alignment fixing structure comprises a tube shell, wherein a transitional block is arranged at the bottom of the tube shell, a photoelectric functional unit is arranged on the transitional block, an optic fiber component is arranged in a center through hole of a tail tube in coaxial mode, a transitional block component is arranged on the transitional block, a glass preformed unit is arranged on the transitional block component, an inner hole is arranged in the glass preformed unit, bare optic fiber of the optic fiber component penetrates through the inner hole of the glass preformed unit, and the transitional block component is connected with the tube shell in electric mode. According to the accurate alignment fixing structure and the alignment fixing method of the optic fiber of the photoelectron device, metallization technology of the optic fiber and weld installation fixing technology of metal solder of the optic fiber are needless. The accurate alignment fixing structure and the alignment fixing method are simple in structure and technology, thereby being little in consuming time and low in cost, and simultaneously overcomes effects on photoelectron device coupling reliability caused by thermal stress factors brought by laser welding technology and epoxy resin glue installation fixing technology in the prior art.

Description

technical field [0001] The invention relates to an optical coupling packaging technology of an optoelectronic device, in particular to an optical fiber accurate alignment and fixing structure of an optoelectronic device and an alignment and fixing method thereof. Background technique [0002] Optoelectronic active devices in the field of optical communications include optical emitters, optical detectors, optical amplifiers and other devices. A kind of optical fiber with certain standard specifications is mainly used for light transmission between various optoelectronic devices and the outside world, so as to realize the transmission of optical signals and light energy between the outside world and optoelectronic devices. For optical transmitters and optical amplifiers, an active alignment method is generally used, which is realized by detecting the output optical power of the laser and adjusting the position of the optical fiber in the XYZ direction. The optical fiber is mo...
