OPTICAL FIBER POLARIZATION CONTROLLER

An optical fiber polarization controller which has compact size by employing wave plates made of short sections of a first optical fiber having inherent birefringence such as a polarization maintaining optical fiber. In the control of the polarization state of input light, a second optical fiber, fo...

Beschreibung
Zusammenfassung:	An optical fiber polarization controller which has compact size by employing wave plates made of short sections of a first optical fiber having inherent birefringence such as a polarization maintaining optical fiber. In the control of the polarization state of input light, a second optical fiber, for example a single mode fiber, connected to the first optical fiber is twisted using fixing knobs, thereby rotating the birefringence axis of the first optical fiber with respect to the second optical fiber.
