Mini Dynamic Polarization Controller – PolaRITE™ III
In response to customer requests for low profile polarization controllers for system integration,General Photonics made a special effort in designing this third generation polarization controller, the PolaRITE™ III, with significantly reduced height and size. The height reduction is especially advantageous for integration in test equipment, fiber sensors, fiber lasers and optical network modules. Due to a special athermal design, the temperature stability is also significantly improved over our earlier version PolaRITE™ II. Like the other products in the PolaRITE™ family, PolaRITE™ III essentially eliminates insertion loss and back reflection with its unique all fiber construction. Combined with General Photonics’ miniature piezo driver card,it can be controlled either by a digital or analog signal to obtain any desired polarization output from an arbitrary input polarization state.

Ordering Information:
Notes: 1260-1650nm and 980-1310 nm are the standard wavelength ranges for this product.
Please specify P grade or A grade if activation loss is important for your application.
*This fiber can handle wavelengths up to 1650nm, but if it is coupled to SMF-28 fiber, the performance may not be quite as good as normal due to mode mismatch.
