Abstract
The utility model relates to a fiber coupling fixture of a butterfly-shaped laser component, which comprises a tube shell. A heat sink is arranged in the tube shell, a laser chip and a fiber pad are fixed on the heat sink, a lens fiber is fixed through being heated by a low-temperature glass solder on the surface of the fiber pad after being coupled and aligned with the laser chip, and the upper surface of the fiber pad is provided with a concave slot for accommodating the low-temperature glass solder. Since the upper surface of the fiber pad is provided with the concave slot, and the concave slot can be designed as a U-type slot, a V-type slot, a semicircular slot, a rectangular slot or a dovetail-shaped slot, the low-temperature glass solder and the lens fiber can be fixed on the fiber pad with the concave slot and can not easily fall off after high-temperature baking and high- and low-temperature circulation experiments, thereby realizing key effect on improvement of the first pass yield of the finished products and the quality stability of the butterfly-shaped packaged laser component, reducing the product manufacturing cost, and facilitating the mass production.
Description
Technical field
The utility model relates to and is used for fiber optic communication field transmission system butterfly laser assembly, and the optical fiber coupling that relates in particular to a kind of butterfly laser assembly is fixing.
Background technology
At present, common butterfly encapsulated laser modular construction as shown in Figure 1, comprise a shell 100, be provided with one heat sink 101 in the shell, be fixed with a chip of laser 103 and an optical fiber cushion block 102 on this is heat sink, one lens fiber 104 is fixed by the low temperature glass solder 105 usefulness LASER HEATING of optical fiber cushion block 102 upper surfaces after being coupled and aligned with chip of laser 103, outwards exports required luminous power.As shown in Figure 2, because the low temperature glass solder 105 in this kind structure is that flat surface contacts with optical fiber cushion block 102, laser assembly is after having passed through the circulation of high-temperature baking and high low temperature, lens fiber 104 produces obscission from optical fiber cushion block 102 surfaces easily together with low temperature glass solder 105, cause lens fiber 104 not keep the Best Coupling state with chip of laser 103, finally influenced the performance of whole butterfly encapsulated laser subassembly product, rate of finished products is lower, increase cost of goods manufactured, be unfavorable for mass production.
Summary of the invention
For overcoming above shortcoming, the utility model provides the optical fiber coupling of a kind of Stability Analysis of Structures, butterfly laser assembly that rate of finished products is high fixing.
For reaching above goal of the invention, the utility model adopts a kind of optical fiber coupling of butterfly laser assembly fixing, comprise a shell, be provided with one heat sink in the shell, be fixed with a chip of laser and an optical fiber cushion block on this is heat sink, after one lens fiber and chip of laser were coupled and aligned, the low temperature glass solder by optical fiber cushion block surface added heat fixation, and the upper surface that is positioned at described optical fiber cushion block is offered a Baltimore groove and is used to hold described low temperature glass solder.
Described Baltimore groove is a U-lag.
Described Baltimore groove is a semi-circular groove.
Described Baltimore groove is a rectangular channel.
Described Baltimore groove is a V-shaped groove.
Described Baltimore groove is a dovetail groove.
Because in said structure, the upper surface of optical fiber cushion block is offered Baltimore groove, low temperature glass solder is fixed on the optical fiber cushion block with Baltimore groove together with lens fiber like this, low temperature glass solder is difficult for coming off in Baltimore groove behind high-temperature baking and the high low temperature circulation experiment, the finished product first-pass yield of butterfly encapsulated laser assembly and the lifting of quality stability are played a key effect, thereby reduced the manufacturing cost of product, helped mass production.

Fig. 1 represents the structural representation of the butterfly encapsulated laser assembly that prior art is general.
Fig. 2 represents the fixing structural representation of optical fiber coupling in the structure shown in Figure 1.
Fig. 3 represents the fixing structural representation of optical fiber coupling of the utility model butterfly laser assembly.
Embodiment
Describe the utility model most preferred embodiment in detail below in conjunction with accompanying drawing.
Optical fiber coupling as shown in Figure 3 is fixing, is the fixing local improvement of optical fiber coupling to butterfly encapsulated laser assembly in the prior art.Improvement is exactly: the upper surface that is positioned at optical fiber cushion block 102 ' is provided with a Baltimore groove 1021 ', is used to hold described low temperature glass solder 105.Baltimore groove 1021 ' can be designed as a U-lag, a V-shaped groove, a semi-circular groove, a rectangular channel or a dovetail groove.
The butterfly encapsulated laser assembly of the utility model structure, concrete making comprises: respectively with chip of laser 103 be provided with the optical fiber cushion block 102 ' sintering of Baltimore groove 1021 ' on heat sink 101, optical fiber clip clamping lens fiber 104, make it to be coupled with chip of laser 103, when coupled optical power reaches maximum, place low temperature glass solder 105 in Baltimore groove 1021 ' and be coated on the lens fiber 104, aiming at low temperature glass solder 105 with the laser beam of laser welder heats, be heated to the low temperature glass solder fusing, laser beam power is slowly reduced cooling, reach low temperature glass solder 105 and the low temperature glass solder and good lens fiber 104 firm being fixed on the optical fiber cushion block 102 ' of coupling that are sintered in the concave groove in advance.
Because in said structure, the upper surface of optical fiber cushion block is offered Baltimore groove, low temperature glass solder 105 is fixed on the optical fiber cushion block 102 ' with Baltimore groove 1021 ' together with lens fiber 104 like this, difficult drop-off behind high-temperature baking and the high low temperature circulation experiment, the finished product first-pass yield of butterfly encapsulated laser assembly and the lifting of quality stability are played a key effect, thereby reduced the manufacturing cost of product, helped mass production.
