Abstract
The utility model discloses a small-sized 1X2 mechanical optical switch which comprises a single-fiber collimator, a reflecting prism, a reflector and a dual-fiber collimator, wherein the single-fiber collimator and the dual-fiber collimator are arranged at the same side of the reflector, the reflecting prism is positioned between the single and dual fiber collimators and the reflector, and the reflecting prism is fixed on a drive mechanism that can move up and down and can cut into and retreat from the optical path. The above structure can drive the reflecting prism to cut into and retreat from the optical path by utilizing the up-and-down moving of the drive mechanism, thus the switching of the optical path can be realized. Meanwhile, because the co-current arrangement of the single-fiber collimator and the dual-fiber collimator changes the original two-end input and output into the single-end input and output, so the size of the optical switch is largely reduced which is easy for installation.
Description
Affiliated technical field
The utility model relates to a kind of 1 * 2 mechanical optical switch that optical communication system, optical tests system, optical sensor system play light path switching effect that is used for, and refers in particular to a kind of 1 * 2 mechanical optical switch of small size.
Background technology
Photoswitch is a kind of switching device, and it can be transformed into another loop or path with the signal in optical fiber, integrated circuit or other optical waveguides from a loop or path effectively.According to principle of work and material therefor, photoswitch can be divided into mechanical type and on-mechanical formula two big classes, and the utility model relates generally to mechanical optical switch, and mechanical optical switch can be divided into moving fiber and mobile optical element dual mode again.Disclose in the existing technology and a kind ofly repeated that performance is good, 1 * 2 mechanical optical switch of mobile refracting prisms (as shown in Figure 1), many shortcomings such as moving fiber poor repeatability, the rebound shake is big to the light path influence, the life-span is short, Insertion Loss is big have been avoided, but still because its input light and output light lay respectively at both sides, account for volume during installation, be difficult to reach the strict demand of modern optical communication.
Summary of the invention
The purpose of this utility model is to provide 1 * 2 mechanical optical switch that a kind of volume is little, be convenient to install.
For realizing above-mentioned purpose, the utility model adopts following structure: a kind of 1 * 2 small-sized machine formula photoswitch, comprise single fiber collimating apparatus, reflecting prism, catoptron and double-fiber collimator, described single fiber collimating apparatus, double-fiber collimator are positioned at catoptron the same side, reflecting prism between list/pair fine collimating apparatus and catoptron, and reflecting prism be fixed on it is moved up and down and the driving mechanism of incision and exit optical on.
Adopt said structure to utilize moving up and down of driving mechanism to drive reflecting prism incision and exit optical, to realize the switching of light path.Simultaneously,, can reduce the volume of photoswitch greatly, be convenient to install because be arranged so that in the same way original two ends input, the output of single fiber collimating apparatus, double-fiber collimator become single-ended input, output.

Embodiment
A kind of 1 * 2 small-sized machine formula photoswitch of the utility model, comprise single fiber collimating apparatus 4, reflecting prism 2, catoptron 3 and double-fiber collimator 1, described single fiber collimating apparatus 4, double-fiber collimator 1 are positioned at catoptron 3 the same sides, reflecting prism 2 between list/double- fiber collimator 1,4 and catoptron 3, and reflecting prism 2 be fixed on it is moved up and down and the driving mechanism 6 of incision and exit optical on.
Principle of work of the present utility model is such: light beam is from an end incident of double- fiber collimator 1, and 3 reflections are coupled into the other end output of double-fiber collimator 1 through catoptron.Move up by adding a driving mechanism 6, make the reflecting prism of fixing on it 2, make light beam pass through reflecting prism 2 and produce the reflection displacement, from 4 outputs of single fiber collimating apparatus.Be the incision and the exit optical of reflecting prism 2, beam direction is changed, thereby reach the purpose that switch switches.
