Embodiment 1

[0015] Such as figure 1 , figure 2 , image 3 with Figure 4 As shown, it includes a base 1 with an upper cover 113, a small platform 2 is fixed on the base 1, and a fixed reflector 5 coated with a high-reflection film on one side is fixed on the baffle 201 of the small platform 2 , The three-fiber collimator 3 is fixed and bonded in the circular opening 114 on the base 1, and the micro relay 7 is fixed and bonded in the base. The cantilever beam 6 and the movable mirror 4 are fixed on the relay 7 One side is coated with a high-reflection film, and the other side is fixed on the baffle 601 of the cantilever 6; the three optical fibers 301, 302, and 303 of the three-fiber collimator 3 are fixed in the same glass tube 304, and the glass The end plane of the tube 304 is coated with an anti-reflection coating, and the plane of the glass tube 304 is fixedly bonded to the lens 305. The three optical fibers 301, 302, and 303 of the three-fiber collimator 3 are arranged in a straight li...

Embodiment 2

[0017] See figure 1 , figure 2 , image 3 with Figure 5 , The three optical fibers in the three-fiber collimator 3 described in Embodiment 1 are arranged in an equilateral triangle, and the rest remain unchanged.

[0018] The typical test results are:

[0019] Dimensions: 16.8mm×10mm×8mm

[0020] Performance index: wavelength range: 1260~1600nm;

[0021] Insertion loss: 0.3dB typical, 0.4dB maximum;

[0022] Polarization dependence: typical 0.05dB; crosstalk: <60dB;

[0023] Switching time: 2~3ms; PMD: 55dB.

Description

Technical field [0001] The invention belongs to the field of integrated optoelectronic devices, and relates to a mechanical optical switch. Background technique [0002] Mechanical optical switches are divided into two categories: mechanical multi-channel 1×N optical switches controlled by micro-precision motors and mechanical optical switches using electromagnetic drive methods, such as movable prism, optical wedge, and 1×N optical switches. 2, 2×2, 1×4 optical switches, etc., are currently available for commercial scale production. [0003] In terms of working principle, the existing commercial mechanical optical switches all use fiber collimator and fiber collimator to align to realize the coupling between the input end and the output end, by moving the collimator or moving optical components, such as prisms. , Reflector, and optical wedge, which change the transmission direction of the collimated beam to realize the switching between the input optical path and the output opti...
