Abstract
The utility model discloses a 1X 2 mechanical type photoswitch includes a single optical fiber beam expander, a refraction lens and a pair of optical fiber beam expander, wherein refraction lens is between single optical fiber beam expander and two optical fiber beam expanders, and fix on can making its translation cut into and withdraw from the drive arrangement of light path, single optical fiber beam expander, drive arrangement and two optical fiber beam expanders all fix on the shell, adopt a novel 1X 2 mechanical type photoswitch of above-mentioned structure, refraction lens is driven by drive arrangement, the distance position of its removal can be through accurate calculation, accurate translation back and forth, the debugging is convenient, good repeatability, more be suitable for batch production, have wide application in optical network and measurement field.
Description
Technical field
The utility model relates generally to and is used for a kind of 1 * 2 mechanical optical switch that optical communication system, optical tests system, optical sensor system play the switching effect.
Background technology
Photoswitch is a kind of switching device, and it can be exactly, selectively the signal in optical fiber, integrated optical circuit or other optical waveguide is transformed into another loop or path from a loop or path.In some existing 1 * 2 mechanical optical switch (as Fig. 1), use refracting prisms and a roof prism, but because the processing problems of roof prism makes it difficult with the pairing use of double-fiber collimator, and crosstalking in the light path is poor, so result of use is unsatisfactory.And another kind of 1 * 2 mechanical optical switch (as shown in Figure 2), then use an angle of wedge prism, make the light that from the single fiber collimating apparatus, comes out enter a road or another road of double-fiber collimator by the refraction of angle of wedge prism, though this kind structural approach is simple, but it is very difficult that debugging is got up, because the end face of angle of wedge prism and collimating apparatus is nearer, and very inconvenient debugging, producing difficulty, therefore is not too desirable.
Summary of the invention
The purpose of this utility model is to provide a kind of debugging convenient, repeats 1 * 2 good mechanical optical switch of performance.
For achieving the above object, the utility model 1 * 2 mechanical optical switch comprises a single fiber beam expander, a refractor and a pair of optical fiber beam expansion device, wherein refractor is between single fiber beam expander and two optical fiber beam expansion device, and be fixed on the drive unit that can make its translation incision and exit optical, single fiber beam expander, drive unit and two optical fiber beam expansion device all are fixed on the shell.
In addition, the utility model can be 1260nm to 1660nm by the concrete wavelength coverage of the light beam of refractor.
Adopt a kind of novel 1 * 2 mechanical optical switch of said structure, refractor is driven by drive unit, and its distance and position that moves can calculate through accurate, accurately translation back and forth, debugging is convenient, good reproducibility, be more suitable for producing in batches, have widespread use at optical-fiber network and fields of measurement.

Embodiment
Shown in Fig. 3-5, a kind of novel 1 * 2 mechanical optical switch comprises single fiber beam expander 1, refractor 2, two optical fiber beam expansion device 3, refractor 2 is between single fiber beam expander 1 and two optical fiber beam expansion device 2, and be fixed on the drive unit 4 that can make its translation incision and exit optical, single fiber beam expander 1, two optical fiber beam expansion device 3 and drive unit 4 all are fixed on the shell 5.Single fiber beam expander 1 and two 3 pairs of light beams of optical fiber beam expansion device expand bundle, so that light beam is assembled better, the concrete wavelength coverage of light beam is 1260nm to 1660nm.
Principle of work of the present utility model is such: light beam A expands the bundle outgoing through single fiber beam expander 1, when refractor 2 is in downward translation state, light beam A is assembled the light path C that enters two optical fiber beam expansion devices 3, i.e. A → C downwards by the refraction of refractor 2 the first half.When refractor 2 makes progress when parallel, light beam A is upwards assembled another light path B that enters two optical fiber beam expansion devices 3 by the refraction of refractor 2 the latter halfs, i.e. A → B, thus realize the change of light path, reach the purpose of switch switching-over light path.The distance of above-mentioned refractor 2 translations makes structure have debugging accurately, the characteristics of good reproducibility through accurate Calculation.
