Background technology
Photoswitch is a kind of optics with one or more optional transmission port, and its effect is to light
Optical signal in transmission line or integrated optical circuit carries out physics switching or logical operation.Light of the prior art is opened
Closing is to select two modes mostly, i.e. one input, two optional outfans, if needing the most defeated
Go out end, then need multiple photoswitches are connected, be unfavorable for integrated.
Summary of the invention
For the deficiencies in the prior art, the invention discloses a kind of one and select four photoswitches.
Technical scheme is as follows:
A kind of one selects four photoswitches, including input waveguide, input collimator, the first prism, the second prism,
Output collimator and four output optical waveguides；Described input waveguide, input collimator, output collimator exist
It is arranged in order in horizontal direction；After four fiber waveguides are positioned over output collimator；Described four output light-waves
Lead and be the most from top to bottom arranged in order；Input waveguide and the 4th fiber waveguide are at same level line
On；First prism, the second prism all can move in and out between input collimator and output collimator；
First prism includes the first vertical and the first inclined plane；Second prism includes that the second vertical and second tilts
Face；The angle of inclination of the second inclined plane is more than the first inclined plane.
The method have the benefit that:
The present invention can accomplish that realizing one in single light shutter device selects the function of four, can reduce device body
Long-pending, the most integrated manufacture.

Detailed description of the invention
Fig. 1 is the schematic diagram of the present invention.As it is shown in figure 1, the present invention includes input waveguide 1, input standard
Straight instrument the 2, first prism the 3, second prism 4, output collimator 5 and four output optical waveguides 6～9.Four
Output optical waveguide 6～9 is the most from top to bottom arranged in order.Input waveguide 1, input collimator
2, output collimator 5 is arranged in order in the horizontal direction；Four fiber waveguides 6～9 are placed on output collimator 5
Afterwards.Input waveguide 1 and the 4th fiber waveguide 6 are in the same horizontal line.First prism the 3, second prism
4 all can move in and out between input collimator 2 and output collimator 5.First prism 3 includes
One vertical and the first inclined plane；Second prism 4 includes the second vertical and the second inclined plane；Second tilts
The angle of inclination in face is more than the first inclined plane.
Fig. 2 is the schematic diagram of first mode.As in figure 2 it is shown, when first prism the 3, second prism 4 all moves
When going out to input between collimator 2, output collimator 5, light path 10 straight line is advanced, and enters the 4th fiber waveguide 9.
Fig. 3 is the schematic diagram of the second pattern.As it is shown on figure 3, when first prism 3 move into input collimator 2,
Between output collimator 5, the second prism 4 removal inputs between collimator 2, output collimator 5, light path
10 are inclined upwardly, and input the 3rd fiber waveguide 9.
Fig. 4 is the schematic diagram of the 3rd pattern.As shown in Figure 4, when first prism 3 removal input collimator 2,
Between output collimator 5, the second prism 4 moves into and inputs between collimator 2, output collimator 5, due to
The angle of inclination of the second inclined plane is more than the first inclined plane, and the acclivitous degree of light path 10 is deepened, input the
Two fiber waveguides 8.
Fig. 5 is the schematic diagram of fourth mode.As it is shown in figure 5, it is equal when working as first prism the 3, second prism 4
When immigration input is between collimator 2, output collimator 5, light path 10 enters the first fiber waveguide 7 as shown in the figure.
Above-described is only the preferred embodiment of the present invention, the invention is not restricted to above example.Permissible
Understanding, those skilled in the art the most directly derive or associate
The oher improvements and changes arrived, within being all considered as being included in protection scope of the present invention.
