Abstract
The present invention relates to a method for manufacturing optical fiber collimators. A relative position between two optical wedge angle slices with fixed angles is regulated to form a wedge angle slice with a required angle for correcting optical beams of a common optical fiber collimator, and in this way, the method for manufacturing an output optical fiber collimator which is parallel or coaxial with the mechanically axial line of a cylindrical packaged optical fiber collimator can be obtained. The present invention makes the positioning process of a conventional collimator simple and convenient.
Description
The present invention relates to the optical fiber collimator field, refer in particular to a kind of method for making of optical fiber collimator.
At present, the method for making of specific collimator is such:
As shown in Figure 1,101 is optical fiber cable, 102 is collimating apparatus, and 103,104 are respectively two low-angle angle of wedge sheets, its principle of work is as follows: measure collimating apparatus emergent light and collimating apparatus machinery axle center angle theta by optical means earlier, the required angle γ of required optical wedge gusset plate that light beam deviation θ is sent as an envoy in calculating inserts light path with angle of wedge sheet to be fixed into firing angle with emergent light again, makes the collimating apparatus exit direction change θ, make by behind the combination angle of wedge sheet light direction and collimating apparatus machinery axis parallel.Close between γ and the θ and be: γ=θ/(n-1), n is an angle of wedge sheet refractive index, realize that this scheme greatest difficulty is because the θ angle is unfixing, therefore when requiring collimating apparatus emergent light and its mechanical axis depth of parallelism very high, the angle of wedge sheet that needs the different angles of big quantity, to mate different collimating apparatuss,, must there be the angle of wedge sheet of respective angles to come corresponding because to any one θ value.To such an extent as in practical operation, bring very big inconvenience to be difficult to realize.
The object of the present invention is to provide a kind of by adjusting the relative position between the two fixed angle optical wedge gusset plates, be combined into required angle angle of wedge sheet and proofread and correct ordinary optic fibre collimating apparatus light beam, obtain optical fiber collimator mechanical axis output optical collimator that parallel or coaxial method for making with cylindrical encapsulation.
Technical scheme of the present invention is achieved in that
Record earlier and made the collimating apparatus outgoing beam and depart from its mechanical axis angle θ
0It departs from required angle of wedge sheet angle γ to calculate corresponding correction again, and getting two angles of wedge is γ
0/ 2 (γ wherein
0＞γ) angle of wedge sheet is made combination angle of wedge sheet, relative position between when extrapolating two angle of wedge sheets combinations angle of wedge and being γ, need the included angle of rotation, fix two angle of wedge sheet relevant positions after φ is adjusted in two angle of wedge sheet positions, the glass tube that will fix two angle of wedge sheets at last is assembled on the GRIN Lens.
Adopt method for making of the present invention to make the collimating apparatus emergent light parallel with mechanical axis, can be applicable to some special occasions, as wish collimating apparatus as the joints of optical fibre, and directly carry out light beam coupling by connector, make conventional collimator positioner process become simpler, convenient.
Now elaborate in conjunction with the accompanying drawings:
Fig. 1 is specific collimator synoptic diagram before.
Fig. 2 is two angle of wedge angle position views.
Fig. 3 is two angle of wedge position views.
Fig. 4 is two angle of wedge position views.
Fig. 5 is the present invention two angle of wedge sheet fixed form synoptic diagram a.
Fig. 6 is the present invention two angle of wedge sheet fixed form synoptic diagram b.
Fig. 7 is encapsulating structure figure of the present invention.
The present invention has adopted a kind of special optical design, and its principle is shown in Fig. 2-4, and being provided with two one sides is square angle of wedge sheet A, B, their corresponding angles of wedge are respectively α, β, and two faces of two angles of wedge are close to, and are not difficult to find out, two angles of wedge are in the same side, and then it makes up wedge angle gamma
1=alpha+beta; Two angle of wedge positions are relative, then make up the angle of wedge and are alpha-beta and (establish α 〉=β), make θ
1Two to be close to limit square edge angle be φ=0 during=alpha+beta, γ
1During=alpha-beta, two are close to neighboring edge included angle=180 °; Like this when φ when 0 changes to 180 °, two angles of wedge combination angle γ varies continuously to alpha-beta from alpha+beta.
If α=β, then making up the angle of wedge will be from 0 → 2 α, records earlier to have made the collimating apparatus outgoing beam and depart from its mechanical axis angle, and it departs from required angle of wedge sheet angle to calculate corresponding correction again.If conventional collimating apparatus maximum deviation angle equals θ
0, corresponding required angle of wedge sheet angle is γ
0, then getting two angles of wedge is γ
0/ 2 angle of wedge sheet is made combination angle of wedge sheet.If actual measurement collimating apparatus light off-axis is θ, calculating the corresponding required angle of wedge is γ, according to when angle of wedge sheet is very little, presses γ=γ
0Cos φ/2 are extrapolated and are combined as the required angle of rotation φ in two angle of wedge sheet edges, γ angle.Again will be in two keies a slice do to rotate in 180 ° of scopes, reach required γ angle after, the relevant position is fixed, and inserts the collimating apparatus light path again, thereby makes the emergent light specific collimator parallel or coaxial with mechanical axis.
As shown in Figure 5, the fixed form of two angle of wedge sheets can adopt adhesive means to allow angle of wedge sheet (square) diagonal angle line length critically equate with the glass tube internal diameter, with four jiaos of angle of wedge sheets and glass tube inwall bonding, can also adopt as shown in Figure 6 mode to fix, allow angle of wedge diagonal line greater than the glass tube internal diameter, allow angle of wedge diagonal line greater than the glass tube internal diameter, less than external diameters such as glass, first is bonded on the glass tube, on second sticking angle of wedge sheet.
In the actual fabrication collimating apparatus, can adopt Fig. 7 mode to encapsulate.701 is optical fiber cable, and 702 is optical fiber head, and 704 is GRIN Lens or other lens, and 703 is stationary cylinder.706,707 are combination angle of wedge sheet, and 706,707 can be at cylinder 705 internal fixation, and the glass tube 705 that installs angle of wedge sheet is assembled on the GRIN Lens also to be fixed, and when rotary glass pipe 705, must have a position to make the collimating apparatus outgoing beam parallel with its collimating apparatus mechanical axis.
In addition, the included angle of two angle of wedge sheets is directly by rotating wherein a slice angle of wedge sheet up to collimating apparatus emergent light fixing realization during with the parallel angle of mechanical axis, and needn't calculate, but pretty troublesome during this way practical operation.
