详细介绍

The FPC family of Polarization Controllers are easily used to convert elliptically polarized light from single mode fiber into linearly
polarized light. It is as simple as coiling a prescribed number of fiber loops into each paddle and adjusting the three paddle positions.
Stress-induced birefringence in the fiber creates three independent fractional “wave plates” to alter the polarization of the transmitted light
in single mode fiber by looping the fiber into three independent spools. 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. (Note: the
desired birefringence is induced by the loop in the fiber and not by twisting of the fiber paddles.)
