Description of Embodiments The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in various different ways as defined and covered by the claims.
As shown in FIG. 1 to FIG. 4, a multi-channel optical passive physical switch provided by this embodiment includes an array disk 10, collimators, a catadioptric module, and a driving module. The collimators include an input collimator 20 and a plurality of output collimators 30 which are all installed on the array disk 10. The input collimator 20 is coaxially fixed at the circle center of the array disk 10 and the output collimators 30 are arranged at an equal diameter on the array disk 10 with the input collimator 20 as the circle center; and the input collimator 20 and the output collimators 30 are located on the same side of the array disk 10. The number of the output collimators 30 may be two or more, and in accordance with the number of the output collimators 30, the multi-channel optical passive physical switch is constructed as an optical switch structure with 1x2, 1x3, ... 1x32 or higher number of channels.
The array disk 10 is in a disk shape, and U-shaped positioning grooves are uniformly formed in the periphery of the array disk 10. The output collimators 30 are fixed in the U-shaped positioning grooves by glue. It should be noted that although the U-shaped positioning grooves are used in this embodiment, the positioning grooves can be processed into V-shaped, square or other shaped positioninggrooves according to processing requirements and processing difficulty, as long as LU101124 the output collimators 30 can be installed and fixed in the positioning grooves.
In addition, there are angles between an output beam of the input collimator 20 and input beams of the output collimators 30, and the angle between the input collimator 20 and each of the output collimators 30 is equal to achieve the optical path connection between the input collimator 20 and the output collimators 30.
As shown in FIGs. 2 and 3, the catadioptric module directly faces the collimators, so that a beam input by the input collimator 20 is refracted and reflected to the output collimators 30. Specifically, a reflecting surface 40 is formed on the catadioptric module; a beam of the input collimator 20 and beams of the output collimators 30 intersect, and the intersection thereof is projected on the reflecting surface 40. The collimators and the reflecting surface 40 meet the following conditions: a+B/2=90°, where a is an angle between the beam of the input collimator 20 and the reflecting surface 40, and ß is an angle between the beam of the input collimator 20 and the beams of the output collimators 30.
The catadioptric module of this embodiment adopts a wedge-shaped specular mirror 50. In order to achieve the connection and switching of the optical path, the following conditions must be met between the collimators and the reflecting surface 40 of the specular mirror 50:
1. The intersection between the beam of the input collimator 20 and the beams of the output collimators 30 is projected on the reflecting surface 40 of the specular mirror 50.
2. a+B/2=90°, where a is an angle between the beam of the input collimator 20 and the reflecting surface 40, and B is an angle between the beam of the input collimator 20 and the beams of the output collimators 30.
The specular mirror 50 that meets the aforementioned conditions enables the beam of the input collimator 20 to be accurately reflected to the output collimators through the specular reflection phenomenon on the reflecting surface 40 of the specular mirror 50, thereby completing the light path connection.
30 In order to achieve switching of the optical path, that is, switching between thebeam of the input collimator 20 and the output collimators 30, the driving module LU101124 may be a stepping motor 60 that may be mounted on the specular mirror 50 and/or on the array disk 10, and a rotating shaft of the stepping motor 60 is coaxially disposed with the input collimator 20 such that the specular mirror 50 and/or the 5 array disk 10 are/is coaxially rotated with the input collimator 20 as the circle center.
The specular mirror 50 is rotated by the precision stepping motor 60 to reflect the beam of the input collimator 20 to the corresponding output collimator 30 on the array disk 10, and an angle of rotation is determined according to the angle of a collimator array at the light-emitting end.
Therefore, an end face 51 of the specular mirror 50 opposite to the reflecting surface 40 also forms the reflecting surface 40, the beam entering the specular mirror 50 is specularly reflected by the end face 51, and the reflected beam also enters the output collimators 30, thereby avoiding the loss of the beam.
The specular mirror 50 of this embodiment is made of an optically dense medium with the refractive index greater than that of the air; and the reflecting surface 40 and/or the end face 51 of the specular mirror 50 are/is coated with a reflective layer.
Therefore, the beam is totally reflected at the end face 51, further reducing the loss of the beam.
The above are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and the equivalent structure or equivalent process transformations made by using the content of the specification and the accompanying drawings of the present invention may be directly or indirectly applied to other related technical fields, and shall be included in a similar way in the scope of patent protection of the present invention.
