General Features

3 Paddles Provide 3 Independently Rotatable Wave Plates
27 mm (Ø1.06″) Fiber Loops
Each Paddle Provides ±117.5° of Rotation
Available Empty or Preloaded With FC/PC- or FC/APC-Terminated Fiber
Replacement Ø900 µm Jacketed FC/PC or FC/APC Patch Cables Available

DKP 3-Paddle Fiber Polarization Controllers use stress-induced birefringence to create independent wave plates to alter the polarization of the transmitted light in single mode fiber. The three fractional wave plates are created by looping the fiber around three independent spools. For the polarization controllers preloaded with fiber, the three paddles are configured to approximate a quarter-wave, half-wave, and quarter-wave plate, in that order, when used at the design wavelength.

The 3PPC270 fiber polarization controller is empty, allowing customers to insert a single mode fiber with a Ø900 µm jacket. Additionally, we have Ø900 µm jacketed FC/PC and FC/APC patch cables available from stock that are suitable for use with these controllers. The other four controllers come preloaded with fiber. The fibers in the preloaded controllers can also be removed and replaced by the user if the controllers are needed for a new application in the future. To ensure proper usage of the controllers, fiber cables must be long enough to achieve the recommended number of loops. For fibers with higher bend loss, we recommend using our Ø56 mm polarization controllers, thereby causing the least amount of bending.

The fiber is secured around three spools and by a clamp at each end of the controller. The spool covers have knobs for easy loading and unloading and the clamps are held in place by screws. If needed, the top of the clamps can be completely removed to load terminated fibers. To secure the controller to the optical table, all 3-paddle controllers have three additional long slots along their base for more mounting options to both metric and imperial optical tables. Two slots at either end of the base accept M6 (1/4″-20) cap screws, while a centered slot accepts M3(4-40) cap screws.
