Overview In order to satisfy the demand of system integration, Joinwit design the 3rd generation polarization controller PolaRITEIII. PolaRITEIII has lower thickness and smaller size and it plays an important role in the integration of testing instruments, optical fiber sensors, fiber lasers and optical modules. The device has a special temperature characteristic. This device can be integrated, and required output polarization state can be obtained by digital or analog signal control. Features 1) No insertion loss 2) No return loss 3) Faster responding time Applications 1.PDM simulation 2.Polarization stabilization 3.Optical fiber sensor 4.Optical fiber laser 5. Testing instrument
