If your application includes single mode fiber and requires linearly polarized light, this Polarization Controller can be easily implemented to convert elliptically polarized light in a single mode fiber into another state of polarization, including linearly polarized light. This polarization conversion is achieved by loading the paddles with a prescribed number of fiber loops to create a fixed waveplate, and adjusting their positions to control the output polarization state.

This polarization controller utilizes stress-induced birefringence to create three independent fractional, fixed wave plates to alter the polarization of the transmitted light in the single mode fiber by looping the fiber around three independent spools. Each spool, in essence, represents a wave plate.

The amount of birefringence induced in the fiber is a function of the fiber cladding diameter, the spool diameter (fixed), the number of fiber loops per spool, and the wavelength of the light. The fast axis of the fiber, which is in the plane of the spool, is adjusted with respect to the transmitted polarization vector by manually rotating the paddles.
