Embodiment
Below, the embodiment that present invention will be described in detail with reference to the accompanying.
Fig. 1 is that the figure of side view is blocked in the part of the optic module of expression first embodiment of the invention.This optic module 10 is as an example, it is the structure that the laser beam sent from semiconductor laser is propagated in optical fiber, for connecting optical fiber in light source side, and use optical connector 50 of the present invention, for the ease of understanding, at first omitted Fig. 2 of the state of optical connector 50 with reference to expression, the major part that relevant light is propagated describes.
As shown in Figure 2, this optic module 10 has: as the semiconductor laser 11 of the sheet state of laser light source; The collector lens 12 of the laser beam B optically focused that will send from this semiconductor laser 11; One end face is that incident end face 13a, other end are for penetrating end face 13b, at the optical fiber of accepting from incident end face 13a by the position configuration of the laser beam B behind collector lens 12 optically focused 13; At least the becket 14 that near the part incident end face of this optical fiber 13 is held fixing glass; The roughly columned short tube (transparent component) 15 of the state of the rear end face 14a of the becket 14 that is configured to be crimped on the incident end face 13a of optical fiber 13 and matches; This short tube 15 and becket 14 are held the fixing sleeve 40 as female component.
Above-mentioned semiconductor laser 11 for example is about luminous width 7 μ m, oscillation wavelength 160～500nm, the GaN of output 200mW is the wide territory of a multimode laser instrument.This semiconductor laser 11 is disposed in the so-called CAN assembly 20 that the glass pane 18 by the light ejaculation window 17a of roughly discoideus bar 16, lid 17, inaccessible this lid 17 constitutes.That is, the heat block 19 of the fixing fine heat radiation property that is made of copper etc. on bar 16 on this heat block 19, for example uses the AuSn scolder that semiconductor laser 11 is installed.After semiconductor laser 11 has been installed like this, weld to bar 16 joint clearances 17, with the inner sealing of CAN assembly 20 by for example low resistance.Need to prove, preferably at the inner filling inert gas of CAN assembly 20.
The inner peripheral surface of the cylindric part 30a of above-mentioned laser stent 30 remains in CAN assembly 20 under (being semiconductor laser 11) state wherein like that above-mentioned, become the state that extends along the optical axis direction of semiconductor laser 11, but this cylindric part 30a also can constitute the lens carrier accommodation section.That is, in the cylindric part 31a of lens carrier 31 with cylindric part 31a and flange part 31b, by bonding, fixedly collector lens 12 such as be pressed into, and this cylindric part 31a is fixed in the cylindric part 30a of laser stent 30.
At this, two stands 30,31 as described later, when keeping the short tube support 32 of short tubes 15 to be crimped on the flange part 31b of lens carrier 31 via sleeve 40, according to make laser beam B behind the optically focused at the front end face 15a of short tube 15 (at this, as described later, the face that the incident end face 13a of optical fiber 13 is joined) go up the convergent mode and regulate mutual optical axis direction relative position, fixing by welding, scolder or bonding agents such as YAG welding etc. under this state.
In addition, short tube 15 and sleeve 40 are fixed in the cylindric part 32a of short tube support 32 by bonding etc.And, make left side among its figure of this short tube support 32 in the flange part 31b upper edge of lens carrier 31 in length and breadth promptly with suitable the moving of direction of light shaft positive cross, adjust to the position that laser beam B combines with optical fiber 13 the most efficiently, in this stationkeeping in flange part 31b.Should fixing also be undertaken by welding, scolder or bonding agents such as YAG welding etc.
At this,, be used for the optical fiber 13 that light propagates originally and also do not remain in the sleeve 40 in fixing moment of short tube support 32 of the flange part 31b of lens carrier 31.Therefore, as mentioned above, for the state of seeing that laser beam B maximal efficiency ground combines with optical fiber 13, replace being used for originally the optical fiber 13 that light is propagated, other adjustment is temporarily remained in the sleeve 40 with optical fiber, adjust the output of the laser beam B of the ejecting end ejaculation of using optical fiber by detections such as laser powermeters from this, at this moment, see that mainly detecting the maximum state of exporting gets final product.Need to prove that lens carrier 31 and short tube support 32 also use the goods of stainless steel as an example.
Then, use optical connector 50 of the present invention (omitting among Fig. 2) that optical fiber 13 is remained in the sleeve 40, thereby the incident end face 13a of this optical fiber 13 become the front end face 15a optics state of contact with short tube 15.Like this, in the optic module 10 that is in Fig. 2 state, the laser beam B of sending from semiconductor laser 11 is restrained on the incident end face 13a of optical fiber 13 by collector lens 12 optically focused.Therefore, laser beam B incides from this incident end face 13a in the core (not shown) of optical fiber 13, and waveguide therein is from the ejaculation end face 13b ejaculation of optical fiber 13.
In this optic module 10, because the control of dust effect that high-octane short wavelength laser beam produces, and confirmed that polluter is attached to the problem (so-called laser pollution) of the light of the optics in the module by end face easily.But, in the present embodiment,, therefore, prevented that polluter is attached on this incident end face 13a from the outside because short tube 15 in crimping on the incident end face 13a of optical fiber 13.Therefore, the output that can prevent the laser beam B that penetrates from optic module 10 reduces because of laser pollutes.Particularly in the present embodiment, because the wavelength of laser beam B is about 160～500nm, laser pollutes and is not easy to produce, and therefore, prevents the particular significant effect that is reduced by its output that causes.
In addition, partly hold near the incident end face at least of optical fiber 13 and be fixed in becket 14, therefore, optical fiber 13 is strengthened by becket 14, and therefore, the vibration that reaches in the use of optic module 10 in propagating can not destroy optical fiber 13 simply.
In addition, in the present embodiment, the rear end face of short tube 15 (incident end face) is the dip plane with respect to the inclined light shaft predetermined angular of collector lens 12.Thus,, turn back to semiconductor laser 11, therefore can prevent to produce so-called reflective noise by oppositely advancing in the light path of this rear end face laser light reflected bundle B before this rear end face.
Have again, as optical fiber 13, use NA and be 0.22, core diameter is the multimode optical fiber about 50 μ m.On the other hand, the incident NA by the laser beam B behind collector lens 12 optically focused is 0.2.In addition, short tube 15 is as an example, formed by the glass of refractive index 1.5, the about 1.0mm of thickness (size of light direct of travel).Under this situation, the NA of the laser beam B of these short tube 15 inside is 0.127.
In addition, will peel off, make it to become the metal wire state, and this part be held be fixed in the becket 14 near the tunicle of the part of the incident end face 13a of optical fiber 13.And, preferred in advance the rear end face 14a of this becket 14 and the incident end face 13a of optical fiber 13 and the front end face 15a of short tube 15 are carried out smoothing processing.
Secondly, with reference to Fig. 3～Fig. 5 the point that optical fiber 13 is connected with short tube support 32 is described.In the present embodiment, the optical connector 50 that is used for this connection is made of adapter shown in Figure 4 60, connector plugs shown in Figure 5 70 of being supported in this adapter 60.
On the other hand, connector plug 70 possess the roughly rectangular-shaped insertion section 70a of profile, respectively be formed at the circle on the left and right sides sidewall of this insertion section 70a opening 70b, be formed at opening 70c, the engaging pawl 70d of the circle on the antetheca of insertion section 70a, portion is fixed with the above-mentioned becket 14 that holds fixed fiber 13 within it.Need to prove that this connector plug 70 is formed by synthetic resin as an example.
Secondly, when joint connector plug 70 on adapter 60, become state shown in Figure 1, thereby optic module 10 is finished.Below, the two combination is described.The front end (with figure right-hand member) of the 70a of portion from adapter 60 inserts the inner face 60a of adapter 60 to connector plug 70 and the mode between a pair of guide portion 60b makes up according to being inserted into.At this moment, the cylindric part 32a of short tube support 32 enters in this connector plug 70 from the opening 70c of connector plug 70, and becket 14 embeds in the sleeve 40 that is fixed in this short tube support 32 then.
Like this with connector plug 70 with suitable pressure be pressed into adapter 60 in side when being lens carrier 31 sides, the rear end face 14a of becket 14 is the front end face 15a crimping of incident end face 13a (with reference to Fig. 2) Yu the short tube 15 of optical fiber 13, becomes the optics contact condition.When keeping this state, simultaneously by the opening 60d of adapter 60 and the opening 70b of connector plug 70, to between the inner peripheral surface of the outer peripheral face of the becket 14 that exposes in the front of short tube support 32 and sleeve 40 during (parts of 41 expressions among Fig. 2) adhesive-applying, this bonding agent soaks between the two, and becket 14 is adhesively fixed in sleeve 40.
As above, if becket 14 and sleeve 40 is bonding, then can becket 14 be crimped on carry out under the situation of the power on the short tube 15 this bonding not discharging, therefore, even the influence that the becket 14 of optics contact and short tube 15 shine because of above-mentioned ultraviolet ray etc. engages, both can not peel off yet for this.In view of the above, can prevent from the light input efficiency of optical fiber 13 is reduced under the influence that produces this part of peeling off.
In addition, above-mentioned opening 60d and 70b are formed at the left and right sides wall of adapter 60 and connector plug 70 respectively, and therefore, the coating of bonding agent can be carried out from the left and right sides, therefore, can make this bonding agent soak into wide region between the inner peripheral surface of the outer peripheral face of becket 14 and sleeve 40.
As bonding agent used herein, the bonding agent about common preferred viscosities 2000～3000cPs.In addition, as this bonding agent, preferably use the thermosetting bonding agent or do not contain the bonding agent of silane couplant.
In addition, as can be known clear and definite from above explanation, the position of the position of the opening 60d of adapter 60 and the opening 70b of connector plug 70 need be set in the position of boundary member of the inner peripheral surface of the outer peripheral face of seeing becket 14 easily and sleeve 40 under the state with connector plug 70 and adapter 60 combinations.
Have, when packing connector plug 70 in adapter 60, the engaging pawl 70d of connector plug 70 is flexibly pressed to the inboard again, and the portion that is stuck that forms is here engaged with the holding section of adapter 60, keeps the assembled state of connector plug 70 and adapter 60.Need to prove, be stuck portion and holding section,, their detailed description is omitted as long as use existing known structure as these.
Need to prove, the optic module 10 of present embodiment is according to laser beam B is formed from the mode that short tube 15 sides incide optical fiber 13, but in contrast, for the light that penetrates from optical fiber 13 is penetrated to short tube 15 sides, and the light that will see through this short tube 15 is used for the optic module of prescribed use, also can use optical connector parts of the present invention, under this situation, also can realize aforesaid effect.
Secondly, the optic module 100 of other embodiment of the present invention is described with reference to Fig. 6.Need to prove, among this Fig. 6, to the identical element annotation same-sign of key element among Fig. 1, the short of special needs of their explanation are just dispensed.
The optic module 100 of present embodiment constitutes according to the mode that two optical fiber 13 are bonded to each other, and for carrying out this combination, and uses optical connector parts 150 of the present invention.These optical connector parts 150 are made of an adapter 160 and two connector plugs 70.
Above-mentioned adapter 160 be basically with the connector plug supporting part of adapter shown in Figure 1 60 mutually back to the structure that forms two, in internal fixation a cylinder part 132 identical with the cylindric part 32a of short tube support 32 shown in Figure 1 arranged.And, be fixed with sleeve 40 at the inner peripheral surface of this cylinder part 132.
The structure with shown in Figure 1 is identical basically for two connector plugs 70, and they are with respect to adapter 160 combination the other way around mutually.This combination is identical with first embodiment.When like this two connector plugs 70 being supported in the adapter 160, and with the mutual crimping of suitable power they the time, the end face 14a that is fixed in the becket 14 in each connector plug 70 is that the end face of optical fiber 13 becomes the optics state of contact each other each other.
When keeping this state, simultaneously by the opening 60d of adapter 160 and the opening 70b of connector plug 70, to between the inner peripheral surface of the outer peripheral face of the becket 14 that exposes in the end of cylinder part 132 and sleeve 40 during adhesive-applying, this bonding agent soaks between the two, and becket 14 is bonded on the sleeve 40.This bonding can certainly carrying out respectively to two beckets 14.
If it is as above that becket 14 and sleeve 40 is bonding, then can carry out each other that this is bonding under the situation of the power of crimping not discharging the end face that makes becket 14, therefore, even the influence that the end face of the optical fiber 13 of optics contact shines by above-mentioned ultraviolet ray each other etc. engage, the two can not peeled off yet.In view of the above, can prevent from the light input efficiency of optical fiber 13 is reduced because of the influence that causes the part that this is peeled off.
Need to prove, as described above described, when two beckets 14 are engaged with each other, also consider to utilize bonding agent that these end faces are bonded to each other.In this case, as the alternate manner of optical connector parts of the present invention, the mode that also can form the part of joining each other according to the end face that can see two beckets 14 is provided with the structure that opening forms on adapter and connector plug.This structure can be bonding with the state of crimping each other with the end face of two beckets 14, therefore, is effective making aspect this bonding reliabilization, the facilitation.
In addition, optical connector parts of the present invention are with respect to the bonding optic module of optics beyond becket 14 discussed above and sleeve 40 or becket 14 and the becket 14 can be suitable for too, and, under these situations, also can realize effect same as described above.
In addition, in each embodiment of above explanation,, used semiconductor laser 11 as sending the light source that incides the light on the optical fiber 13, but the invention is not restricted to semiconductor laser, also go for the situation that other solid state laser etc. is used as light source.For example using oscillation wavelength to be under the situation of solid state laser of scope of 160～350nm described effect of the present invention before also having confirmed.
