Abstract

Both ends male means when being put the utility model is related to a kind of BAR optical coating of realization, it is characterised in that：Including glass gasket and it is located at the groove on glass gasket for being put into BAR items；It is spaced apart BAR items in the groove, is placed between BAR items two-by-two and accompanies item, the periphery plane for accompanying item thin compared with BAR items and to be supported on glass gasket groove.The utility model is simple in structure, and processing cost is low, and practicability is high, both ends protrusion when can be put with simple and convenient reliable BAR optical coating of realization, solves the problems, such as that the end faces BAR optical film is damaged in coating process, is conducive to the yield for improving product.

Description

Realize both ends male means when BAR optical coating is put

Technical field：

Both ends male means when being put the utility model is related to a kind of BAR optical coating of realization.

Background technology：

The preparation of optic communication semiconductor laser represents the development side of advanced micro-nano technology and device integration process To having obtained the great attention of every country in the world.The semiconductor laser of optic communication is the core of fiber optic communication.At present Optic communication mainly carries out epitaxial growth using INP substrate slices with semiconductor laser and rear end processes, the BAR items in rear end processes End face optical coating technique is to ensure the critical process of laser parameter.

BAR optical coating is exactly to plate corresponding optical medium film layer at the both ends of BAR items, is to ensure in coating process Coating quality, BAR items cannot continuously be put, and one is pressed from both sides between BAR items and accompanies item, accompany a width ratio BAR items slightly narrow, and BAR items is made to put Slightly prominent when putting, existing method can only ensure have protrusion, another side not to have on one side, when the plated film over there not protruded in this way Just there is film layer and be adhered phenomenon, the situation of film layer breakage is just will appear when BAR items detach, yield is affected, and how to protect BAR both ends, which are all protruded, when card BAR items are put accompanies an end face, this is the emphasis and difficult point of research.

Invention content：

It protrudes from the purpose of this utility model is to provide both ends when a kind of BAR optical coating of realization is put and accompanies an end face Device protrudes to being advantageously implemented BAR both ends and accompanies an end face, and it is damaged to solve the end faces BAR optical film in coating process Problem.

The utility model realizes both ends male means when BAR optical coating is put, it is characterised in that：Including glass gasket With the groove being located on glass gasket for being put into BAR items；It is spaced apart BAR items in the groove, is put between BAR items two-by-two It sets and accompanies item, the periphery plane for accompanying item thin compared with BAR items and to be supported on glass gasket groove.

Further, the groove depth of above-mentioned groove is 10um ~ 20um.

Further, the material of above-mentioned glass gasket is K9 glass.

The utility model realizes both ends male means application method when BAR optical coating is put, first in glass gasket 1 BAR items 3 are put into groove 2；Then it is placed in 3 outer periphery of BAR items and accompanies item 4, it is described to accompany item 4 thin compared with BAR items and be supported on glass The periphery plane 5 of gasket groove；Then item and BAR items are accompanied in fixation；Glass gasket 1 is finally withdrawn, BAR top and lower end are made It is exposed at and accompanies a upper and lower.

The beneficial effects of the utility model：

The utility model is simple in structure, and processing cost is low, and practicability is high, can be with simple and convenient reliable realization BAR item light Both ends protrusion when plated film is put is learned, solves the problems, such as that the end faces BAR optical film is damaged in coating process, is conducive to improve the good of product Rate.

Description of the drawings：

Fig. 1 is the sectional view of the utility model glass gasket；

Fig. 2 is that the utility model glass gasket bears BAR items and accompanies the organigram of item；

Fig. 3 is the vertical view organigram of Fig. 2.

Specific implementation mode：

The utility model method is described in further detail with reference to embodiment.It should be strongly noted that this The protection domain of utility model should include but not limited to the technology contents disclosed in the present embodiment.

The utility model realizes that both ends male means include glass gasket 1 and are located at glass when BAR optical coating is put Groove 2 on gasket for being put into BAR items 3；It is spaced apart BAR items 3 in the groove 2, is placed between BAR items two-by-two and accompanies item 4, the periphery plane for accompanying item thin compared with BAR items and to be supported on glass gasket groove.

Further, for reasonable design, the groove depth of above-mentioned groove is 10um ~ 20um, and the material of above-mentioned glass gasket is K9 glass.

The beneficial effects of the utility model：

As shown in Figure 1, the groove width of glass gasket and the implementation method of groove depth are, glass gasket groove width is according to the length of BAR items Du Laiding, other regions are covered with high temperature gummed tape, then glass gasket are placed in hydrofluoric acid solution, pass through the control corrosion rate time To realize groove depth.

As shown in Fig. 2, glass gasket is placed in plane, it is placed on glass gasket according to accompanying a BAR items interval to stand, Wherein BAR items are placed in slot, and item is accompanied to be placed in outside slot, are fixed with coating clamp after the completion of all putting, and glass gasket is removed, Realize that BAR upper/lower terminal is all raised.

The above is only the preferred embodiment of the present invention, it is all done according to present utility model application the scope of the claims it is equal Deng variation and modification, it should all belong to the covering scope of the utility model.

Claims
