Description
The utility model relates to a kind of optical switch device, particularly a kind of mechanical optical switch.
Photoswitch is a kind of one or more selectable transmit pories that have, and can change mutually or the device of logical operation light signal in optical transmission line or the integrated optical circuit.Light opens the light and can be used for optical fiber telecommunications system, optical fiber network system, optical fiber measurement system or instrument and optical sensor system, plays switch switching effect.
The mechanical switch kind is more, and scheme is various, and performance respectively has relative merits.1 * 2 and 2 * 2 mechanical switch on market at present, the following scheme of wherein a kind of employing, shown in Fig. 1 (a), its ultimate principle be utilize two uniformly-spaced the diplopore kapillary make the two-beam that double-fiber collimator sends identical crossing angle characteristics arranged before lens.Adjust two twin-beam collimating apparatuss and can be achieved as follows function, see Fig. 1 (a), Fig. 1 (b).Wherein 101,102 be double-fiber collimator, 1,2 is respectively optical fiber input, the output terminal of collimating apparatus 101; 3,4 are respectively optical fiber input, the output terminal of collimating apparatus 102.103 is a plane mirror.
In Fig. 1 (a), realize port one → 4
Port 3 → 2
In Fig. 1 (b), introduce plane mirror, regulate the plane mirror position, can realize
Port one → 2
Port 3 → 4
So control by machinery when plane mirror, go into the light path from light path is circumscribed, promptly switch realizing, become 1 → 2 by 1 → 4; Become 3 → 4 by 3 → 2.The incision of plane mirror and exit optical are promptly realized the switch handoff functionality, and this construction of switch characteristics are the little and compact conformations of volume, are to release one of minimum a kind of switch of volume in the mechanical switch on the market.
In optical passive component, output terminal collimating apparatus emergent light is mostly by being accepted by the opposite collimating apparatus behind a series of optical elements and exporting, simultaneously do not introduce optical loss than the great talent by optical fiber cable bending diameter in the hand optical fibre device, so its optical fiber cable is distributed in the device both sides mostly, when passive device was installed in system like this, its device and optical fiber cable needed than large space.If at fiber optic passive device, optical fiber cable can take up space greatly making things convenient for optical passive component itself to install with the light turnover optical fiber cable that reduces passive device greatly in device one side.So it is that fiber optic passive device is pursued that the single-ended input and output of optical passive component guarantee little this of volume simultaneously, but is difficult for one of target that realizes.
The purpose of this utility model is: design a kind of new mechanical formula photoswitch, achieve input-output optical fiber at the same end of device.
To achieve these goals, the utility model adopts following structure, a kind of mechanical optical switch is by collimating apparatus, catoptron, compositions such as housing, optical fiber head in the collimating apparatus contains three optical fiber and is fixed on housing one end, wherein one is the input optical fibre line, two is the output optical fibre line, prism or prism group are set between collimating apparatus and catoptron, one catoptron is fixed on the housing other end, one flexible mirror is arranged between prism or prism group and the stationary mirror, and be fixed on connecting rod that current-collector links to each other on, by current-collector switch and corresponding wheelwork switching activity catoptron, form two light paths, promptly form 1 * 2 switch.
The utility model can also adopt following structure, optical fiber head contains n+1 optical fiber cable and is fixed on housing one end in the collimating apparatus, wherein 1 optical fiber cable is the input optical fibre line, n optical fiber cable is the output optical fibre line, correspondingly n catoptron is set at the other end, one of them is fixed on the other end, faceted pebble or prism group are arranged between collimating apparatus and the catoptron, n-1 flexible mirror is all between prism or prism group and stationary mirror, by current-collector switch and corresponding wheelwork switching activity catoptron, change light path in regular turn, form 1 * n switch.
Adopt the mechanical optical switch of said structure design, switch is compressed to littler volume, prior art can realize that input, output optical fibre at the same end of body, reduce device and take up room relatively, makes the photoswitch range of application wider, uses convenient.
Specify below in conjunction with example:
Fig. 1 [(a) and (b)] is the prior art synoptic diagram.

As Fig. 2, collimating apparatus 204 is three optical fiber collimators, three optical fiber emergent lights of collimating apparatus at grade, prism 205 will be limited to same plane from three light beams that three optical fiber collimators come out, and be the three beams directional light with three beam collimations.Prism 206 energy will be by optical fiber 201 incident lights and optical fiber 202, and difference A before and after optical fiber 203 emergent lights meet at respectively is on the B.
Actual light path is not from optical fiber 201, optical fiber 202, optical fiber 203 directional lights of outgoing simultaneously, and only from optical fiber 201 outgoing collimated light beams, light beam is through prism 205, and prism 206 is to A point place, the place puts into free cheek catoptron 207 at the A point, and free cheek catoptron 207 sends the light reflection with optical fiber 201.Get back to optical fiber 202 by prism 206,205 again; Flexible mirror 207 is put on the current-collector switch or on the corresponding wheelwork.When the anti-mirror 207 of free cheek shifts out light path, when promptly forming 207 ＇ positions, the light that optical fiber 201 sends continues to arrive B point position forward, and B disposes a stationary mirror 208, and it reflects optical fiber 201 emergent lights through prism 206, and prism 205 is got back to optical fiber 203.If as passage 1, optical fiber 202 is as passage 2 with optical fiber 201; Optical fiber 203 is as passage 3.Reflection is switched plane mirror 207 ＇ and is entered and return passage like this, promptly forms 1 → 2 and transfers 1 → 3 to and promptly form 1 * 2 switch.Prism 205 and prism 206 can unite two into one, as shown in Figure 3.
This patent can be used for the n+1 optical fiber collimator.As shown in Figure 4, prism 302 and prism 303 with the emergent light of optical fiber 1 at R
