Abstract:
1. A 2×2 mechanical optical switch, comprising: a base, having a central hole; a first input collimator and a first output collimator, disposed on a plane of the base, and forming a first transmission optical path between the first input collimator and the first output collimator that passes through a central point; a second input collimator and a second output collimator, disposed on the plane, and forming a second transmission optical path between the second input collimator and the second output collimator that passes through the central point; a double-sided reflection ultra thin mirror, disposed at the mirror switch and passed through the central hole, such that when the double-sided reflection ultra thin mirror leaves the central point, a signal of the first input collimator is sent to the first output collimator along the first transmission optical path, and a signal of the second input collimator is sent to the second output collimator along the second transmission optical path, and when the double-sided reflection ultra thin mirror stays at the central point, a signal of the first input collimator is sent to the second output collimator along a first reflection optical path, and a signal of the second input collimator is sent to the first output collimator along a second reflection optical path; a mirror switch, disposed in the central hold of the base, for controlling the double-sided reflection ultra thin mirror to leave or stay at the central point by swaying the mirror switch; and an external mirror switch coupled to the mirror switch for increasing the sway amplitude of the mirror switch.
