Newport's Polarization Controllers are designed for those working with polarization sensitive devices and systems. The patented design, based on an all-fiber Babinet-Soleil compensator, can be used to generate any polarization state at the output from an arbitrary input polarization state.The rotatable fiber squeezer mechanism adds no intrinsic loss or back-reflection, and allows polarization adjustments in two quick and easy steps. In addition to their compact size, the controllers are insensitive to variations in fiber material, diameter or wavelength of the light passing through the fiber.The In-Line version, F-POL-IL, offers great flexibility by allowing the insertion of a 250 µm buffered optical fiber. The Pigtailed version, F-POL-PT, includes two 9/125 µm fiber pigtails, with 900 µm jackets, with no connectors, FC/UPC, or FC/APC connectors. The no pigtail version, F-POL-PC, is available with either FC/PC or FC/APC connectors.
Newport's manual polarization controllers are based on the Babinet-Soleil Compensator. An all-fiber polarization controller based on this technique is shown in Figure below. The device comprises a fiber squeezer that rotates around the optical fiber. Applying a pressure to the fiber produces a linear birefringence, effectively creating a fiber wave plate whose retardation varies with the pressure. Simple squeeze-and-turn operations can generate any desired polarization state from any arbitrary input polarization.
