Fiber Based Scientific Research Products Optical Polarization Controller
Optical Polarization controller MINI 2
A fiber polarization controller can be used for manipulating the polarization state of light in fibers. That can be important e.g. for interferometers and fiber lasers
The 2-paddle polarization controllers use two quarter-wave plates to transform an arbitrary polarization state into any other polarization state. In this configuration, however, the control of the polarization will be coupled between the two paddles. These controllers allow complete control of the output polarization state over a broad range of wavelengths (300 to 2100 nm).
The retardation per paddle is a function of the loop number and the cladding diameter of the fiber if the loop diameter is fixed. The retardation, in radians, is plotted for 1, 2, 3, and 4 loops per paddle for a fiber with cladding diameters of 80 µm and 125 μm
Opto Electronics offers a variety of fiber-based products designed to manipulate the polarization state of light in a fiber.
