Abstract
An optical switch includes two optical input terminals, two optical output terminals, two reflecting devices and a movable device. The optical input terminals are used to receive light rays. The two reflecting devices are positioned at fixed positions, and the movable device reflects light rays. When the position of the movable device moves, the light rays are reflected by one of the reflecting devices and are selectively output from the optical output terminals.
Claims20
An optical switch comprising:
- two optical input terminals respectively receiving a light ray;
- two optical output terminals;
- two reflecting devices respectively fixed at a predetermined position;
- and
- a movable device for reflecting the light ray;
- when the movable device moves, the light ray is reflected by one of the reflecting devices and is selectively output from the optical output terminals.

An optical switch comprising:
- a first input terminal for receiving a first light ray;
- a second input terminal for receiving a second light ray;
- a first output terminal;
- a second output terminal;
- a first reflecting device disposed at a fixed position;
- a second reflecting device disposed opposite to the first reflecting device;
- and
- a movable device for switching optical paths of the first and second light rays;
- wherein when the movable device is disposed between the first and second reflecting devices, the first light ray is reflected by the movable device, the second reflecting device and the movable device in order to be received by the second output terminal, and the second light ray is reflected by the movable device to be received by the first output terminal;
- when the movable device is removed, the first light ray is reflected by the first reflecting device to be received by the first output terminal, and the second light ray is reflected by the first reflecting device to be received by the second output terminal.
