Product Description:

Polarization controllers allow one to convert any input polarization to any desired output polarization. The device combines the compact size and ease of use of standard bulk optics systems with low costs, low losses, and low backreflections.

The controller works by applying pressure with an adjustable clamp. The pressure on the fiber causes a birefringence within the fiber core, causing the fiber to act as a fractional wave plate. Varying the pressure varies the delay between the fast and slow polarization components. The clamp is rotatable, allowing one to change the direction in which the stress is applied. This allows any output polarization to be achieved. The process is simple and quick. Output polarizations exceeding 40 dB can be routinely achieved in seconds.

The fiber polarization controller works with singlemode fiber of any wavelength. The controller does not work with multimode or Polarization Maintaining (PM) fiber. For multimode and PM fiber OZ Optics still offers their standard series of polarization rotators and analyzers (refer to the Polarization Rotators / Controllers / Analyzers data sheet).

All fiber polarization controllers are offered in three versions. The in-line polarization controller can be inserted onto a customer’s own singlemode fiber. We now offer this unit in a miniature size housing, for applications where space is critical. It can be used with any wavelength singlemode fiber. The in-line version is designed to work with only 250 micron and 400 micron jacketed fibers. Secondly, a pigtailed version is also offered. This version is available with any size of cable or fiber, and with your choice of connectors. Finally, a connector receptacle style controller is available, using a short section of fiber terminated with female receptacles. For further information contact OZ Optics.
