Abstract
The invention discloses a kind of preparation method of fiber coupler, it comprises the following steps：1）, treat in signal optical fibre to etch the arc groove being adapted with each pumping optical fiber external diameter on the surface of weld portion respectively with femto-second laser, each pumping optical fiber is fitted tightly on signal optical fibre in corresponding arc groove respectively to form fibre bundle；2）, above-mentioned fibre bundle is placed on and drawn on cone machine, draw cone machine to carry out fusion drawn to the joint portion of signal optical fibre and pumping optical fiber, so that N roots pumping optical fiber and signal optical fibre are connected to form one.Using above method, fused biconical taper is carried out after each pumping optical fiber is positioned on the surface of signal optical fibre by arc groove again, the relative position of each pumping optical fiber and signal optical fibre can keep stable during cone is drawn, and will not produce displacement, therefore the quality of fused biconical taper is higher, more stable.
Description
Technical field
The present invention relates to laser field, more particularly to a kind of preparation method of fiber coupler.
Background technology
The technology of fused biconical taper is typically used when prior art makes fiber coupler, it is specific as follows：First by N root pumpings
Optical fiber is centered around outside a signal optical fibre and forms fibre bundle, is then placed on fibre bundle and draws fused biconical taper on cone machine to connect to form one
Body.The above method draws the method bored using violence, and peripheral pumping optical fiber not can determine that position during cone is drawn, therefore molten
The poor repeatability connect, every pumping optical fiber position are difficult to fix, it is impossible to the phase of adjustment pumping optical fiber and signal optical fibre as needed
To position with adjust the optical quality of output light and improve coupling efficiency.
The content of the invention
In order to solve deficiency of the prior art, it is an object of the invention to provide a kind of welding quality it is stable, can be by
The preparation method of pumping optical fiber and the fiber coupler of signal optical fibre relative position need to be adjusted.
To achieve the above object, the present invention uses following technical scheme：
N roots pumping optical fiber and a signal optical fibre are passed through melting by a kind of preparation method of fiber coupler, the preparation method
Draw taper integral, wherein N is the integer more than or equal to 1；The preparation method specifically includes following steps：
1）, treat to be etched respectively with femto-second laser on the surface of weld portion in signal optical fibre and be adapted with each pumping optical fiber external diameter
Arc groove, each pumping optical fiber is fitted tightly on signal optical fibre in corresponding arc groove respectively to form fibre bundle；
2）, by above-mentioned fibre bundle be placed on draw cone machine on, draw cone machine melting drawing is carried out to the joint portion of signal optical fibre and pumping optical fiber
Stretch, so as to which N roots pumping optical fiber and signal optical fibre are connected to form one.
The axial both ends of each arc groove pass through arcwall face transition.
The present invention uses above technical scheme, and each pumping optical fiber is positioned on the surface of signal optical fibre by arc groove
Carry out fused biconical taper again afterwards, the relative position of each pumping optical fiber and signal optical fibre can keep stable during cone is drawn, will not
Displacement is produced, therefore the quality of fused biconical taper is higher, more stable；Can be according to need in addition, being processed using femto-second laser
Etch the position of required arc groove and required cut-out and there is very high machining accuracy, therefore the hot spot of output light
Quality can be adjusted as needed.
Brief description of the drawings
The present invention is described in further details below in conjunction with the drawings and specific embodiments：
Fig. 1 is step 1 of the present invention）In pass through the schematic diagram that arc groove and each pumping optical fiber coordinate on signal optical fibre surface；
Fig. 2 is step 2 of the present invention）Middle fibre bundle passes through the schematic diagram after fused biconical taper.
Embodiment
As shown in one of Fig. 1 or Fig. 2, a kind of preparation method of fiber coupler of the present invention, preparation method is by N root pump lights
Fibre 2 forms one with a signal optical fibre 1 by fused biconical taper, and wherein N is the integer more than or equal to 1, and N in the present embodiment=
6；Preparation method specifically includes following steps：
1）, as shown in figure 1, treating to be etched respectively and each pump light with femto-second laser on the surface of weld portion in signal optical fibre 1
The arc groove that fine 2 external diameters are adapted, corresponding arc groove on signal optical fibre 1 is fitted tightly over by each pumping optical fiber 2 respectively
It is interior to form fibre bundle；Wherein, the axial both ends of each arc groove pass through arcwall face transition；
2）, draw on cone machine as shown in Fig. 2 above-mentioned fibre bundle is placed on, draw combination of the cone machine to signal optical fibre 1 and pumping optical fiber 2
Portion carries out fusion drawn, so as to which 6 pumping optical fibers 2 and signal optical fibre 1 are connected to form one.
The above method is melted again after using arc groove, each pumping optical fiber 2 is positioned on the surface of signal optical fibre 1
Cone is drawn, the relative position of each pumping optical fiber 2 and signal optical fibre 1 can keep stable during cone is drawn, and will not produce displacement, because
The quality of this fused biconical taper is higher, more stable；In addition, the position of arc groove can be etched as needed using femto-second laser
And machining accuracy is high, so as to adjust the optical quality of required output light and improve coupling efficiency.
