Accurate alignment fixing structure and alignment fixing method of optic fiber of photoelectron device

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.
