Optical switch
First Claim
Patent Images
1. An optical switch for selectively reflecting and passing a light beam, which comprises:
- a substrate;
a magnetic object installed on one surface of the substrate for providing a magnetic field;
a rotator pivotally installed on the substrate, has a mirror and a magnetic material on its surface, and, under the interactions with the magnetic field, forms two locking potential wells to lock the rotator at a reflection position for reflecting the beam and a non-reflective position for passing the beam; and
a driving device installed close to one surface of the substrate corresponding to the rotator for providing a driving force to switch the rotator between the two locking potential wells.

Abstract
An optical switch is disclosed. A lock magnetic field is provided on the sides of a rotator with a magnetic surface. The magnetic field has a potential with two minima as reflective and non-reflective positions. At the reflective position, the reflective mirror on the rotator reflects light beams. The beam goes through when the rotator is at the non-reflective position. At the same time, the magnetic field firmly locks the rotator at its position. When a driving force is imposed on the rotator; it rotates from its current position to the other position and gets locked at the new position.
