Abstract:
1. A polarization control device for controlling state of polarization (SOP) of light propagating along an optical fiber, the polarization controlling device comprising: drive motor means comprising a stator and a tubular rotor; fiber squeezer means mounted to the tubular rotor for rotation therewith; said optical fiber extending through said tubular rotor and said fiber squeezer means, said fiber squeezer means squeezing a portion of said fiber to secure said fiber to said fiber squeezer means for rotation therewith and to induce a predetermined linear birefringence in said portion; the drive motor means being operable to rotate the fiber squeezer means and therewith said portion of the optical fiber and thereby control said state of polarization (SOP) of light propagating through said optical fiber.
