AI Technical Summary

Problems solved by technology

This structure can form a multi-channel optical switch. Its shortcoming is that the distance between the movable mirror and the electrode is not large because only the micromechanical process is used, so the number of states that the mirror can produce different displacements and rotations is limited, and the number of states of the optical path is limited. The number of switches is not large, which also limits the realization of large M×N optical switches

Embodiment Construction

[0014] Such as figure 1 As shown, the overall structure of the present invention mainly includes: polyhedral prism 1, rotating part 2, electromagnetic drive part 3, substrate 4, bearing 5, rotating shaft 6, casing 7, polyhedral prism 1 is fixed on the output end of rotating shaft 6, rotating part 2 is set Between the double electromagnetic drive parts 3 on the upper and lower sides in the shell 7, it is fixedly connected with the rotating shaft 6, and rotates or is still at the same time. The base plate 4 is also arranged outside the double electromagnetic drive parts 3 on the upper and lower sides of the shell 7. Supported by bearing 5, N in the 1×N optical switch represents the number of reflected light paths, and N can be equal to 24 or more paths. The polyhedral prism 1 is directly installed with the rotating shaft 6, which makes the overall structure compact, improves the switching speed, and is easy to control.

Description

technical field [0001] The invention relates to a micro switch, in particular to a micro rotary 1×N optical switch, which belongs to the field of micro optical switches. Background technique [0002] In recent years, the "integrated micro-opto-electromechanical system" (MOEMS) produced by the combination of micro-mechanics, micro-electronics, and micro-optics has provided a new means for the realization of new optical fiber communication devices. Micro-mechanical optical switches made with micro-electromechanical systems (MEMS) technology not only have all the advantages of mechanical optical switches, but also have a small size (millimeter order or smaller), and the manufacturing process is compatible with the manufacturing process of large-scale integrated circuits. Mass production and optical integration or optoelectronic integration, low cost and good repeatability. In particular, its switching time can be greatly shortened, reaching the microsecond level. Through lite...
