Abstract
The switch includes double optical fibre core collimator, single optical fibre core collimator and switching unit, of which two collimator can be used to emitt and receive lightbeam and they are set in opposite position. The switching unit with reflector set movably in between the two collimators can selectively reflect light beam issued from double optical core collimator to itself for receiving or to let it forward on continuously for being received by single optical fibre core collimator so this is the way that the switching of light path is achieved.
Description
Technical field
The present invention relates to a kind of mechanical optical switch, be used for the direct of travel of control bundle, particularly under the situation that does not change former switching device shifter, optionally 2 * 1 photoswitch frameworks are extended for 2 * 2 photoswitches and use.
Background technology
In general, photoswitch (optical switch) is used for the direct of travel of control bundle, and be used for light beam and march to somewhere whether light beam switching, switching as switch, therefore photoswitch optionally make one in advancing light beam from its reflex to other direction along the direction of advancing, and continue at this other direction and advance, or be that its continuation is advanced along its direct of travel, and the main mode of photoswitch control bundle is with beam reflection with catoptron.
At present, the patent of photoswitch is existing many, as United States Patent (USP) case No. 4239331, No. 4303303, No. 4322126, No. 4790621, No. 4948223, No. 5000534, No. 5642446, No. 5661827, No. 5742712, No. 6044186 and No. 6215919 patent case.
No. 4239331 of above-mentioned United States Patent (USP) case, No. 4303303, No. 4322126, No. 4790621, disclosed photoswitch is to do the switching of position by the catoptron that switching device shifter will be connected in it in No. 5000534 and No. 5642446, and switching device shifter all adopts the skew or the mode of rotation to change the position of catoptron in these six patent cases, and these six patent cases have following characteristics respectively: No. the 4239331st, the U.S., No. 4303303, No. 4,322,126 three patent cases all have the function (mechanical latch) of fastening lock, and its switching device shifter that is connected with catoptron all adopts electromagnetic mode to change the position of catoptron, and then switching-over light path, but can there be mechanical wear in this kind mechanism under long-term the use, and influence its degree of stability, in addition, the general using prism changes optical propagation direction because the angle of light entrance prism is very responsive, easily cause the increase of inserting loss, moreover its employed several single-core fiber collimating apparatuss also have the excessive anxiety of the volume of causing; Then use too much package count as for No. 4790621 patent case of the U.S., and complex structure, even its switching device shifter switched mirror to the stability of two positions also is worth discussion, but it has the advantage of fastening lock function; No. 5000534 patent case of the U.S. is position and then the switching-over light path that reaches switched mirror in rotary manner, but its volume is excessive, and do not have the function of fastening lock; No. 5642446 employed package count of patent case of the U.S. is too much, and complex structure, and has the excessive shortcoming of volume.
All adopt the actuator moving fiber with No. 6044186 patent case No. 4948223 of the United States Patent (USP) case, but be used for the mode difference of driving actuator in the two patent cases: No. 4948223 patent case is to switch with electromagnet to come moving fiber, No. 6044186 then is to come moving fiber with two piezoelectrics (bimorph), common drawback as for both then is because of it is that the elastic force that utilizes optical fiber to contact with the bottom surface is kept optical fiber in its position, therefore can doubt to some extent for degree of stability of switching or repeatability.
In No. 5661827 patent case of United States Patent (USP) case, its switching device shifter is by magnet control, the switching-over light path with the position of skew catoptron, but it has the too much shortcoming of package count, therefore causes the cooperation of each inter-module to be difficult for, so be difficult for a large amount of production.
In No. 5742712 patent case as for the United States Patent (USP) case, be to adopt relay mobile mirror position and switching-over light path, but it does not have the function of fastening lock.
And the angle that is used for the wedge shape optical module of switching-over light path in No. 6215919 patent case of United States Patent (USP) case must have certain requirement, can switching-over light path, and therefore have and make the shortcoming that is difficult for.
For these reasons, it is very important developing the mechanical optical switch with following function:
1. optionally make one in advancing light beam from its reflex to other direction along the direction of advancing, and continue at this other direction and advance, or be that its continuation is advanced along its direct of travel.
2. has the function of catoptron stably being fastened two positions that lock in switching.
3. make the employed package count of this mechanical optical switch few, and volume is little, and simple structure is arranged and be easy to manufacturing.
Summary of the invention
Fundamental purpose of the present invention is provides a kind of mechanical optical switch, to reach the purpose of switching-over light path.
Secondary objective of the present invention is provides a kind of mechanical optical switch, catoptron is stably fastened lock in reflection position and in the purpose of non-reflection position to reach.
Another purpose of the present invention is provides a kind of mechanical optical switch, and the combine component number is few, volume is little to reach, simple structure and the purpose that is easy to make.
Mechanical optical switch disclosed according to the present invention, optionally reflect a light beam and make it current, the present invention includes the twin-core fiber collimating apparatus, single-core fiber collimating apparatus and switching device shifter, wherein the twin-core fiber collimating apparatus comprises that launching fiber and first receives optical fiber, the single-core fiber collimating apparatus comprises that second receives optical fiber, and the single-core fiber collimating apparatus the relative twin-core fiber collimating apparatus in position is set, then comprise catoptron as for switching device shifter, this catoptron is arranged between twin-core and single-core fiber collimating apparatus movably, and catoptron has two and stable fastens lock position, corresponds respectively to the reflection position of folded light beam and allows the current non-reflection position of light beam.
When the catoptron of switching device shifter is positioned at its reflection position, the light beam that launching fiber sent by the twin-core fiber collimating apparatus can receive optical fiber through mirror reflects to the first, and when the catoptron of switching device shifter is positioned at its non-reflection position, the light beam that launching fiber sent by the twin-core fiber collimating apparatus then can continue to march to the second reception optical fiber, and by its reception.
