SPECIAL POLARIZATION INSTRUMENTS COMPONENTS APPLICATION ACCESSORIES GUIDE FAQS TIMING/DELAY MANAGEMENT MODULES POLARIZATION MANAGEMENT MODULES General Photonics Corporation 909.590.5473 http://www.generalphotonics.com -19- Controlling polarization state has never been easier: This instrument has four operational modes for complete polarization control: variable speed polarization scrambling, manual polarization adjustment, polarization function generation, and externally triggered scrambling. In polarization scrambling mode, the instrument uniformly scans through all SOP’s on the Poincaré Sphere with user selectable speed and waveform, at frequencies ranging from 0.01 Hz to 6kHz. Alternatively, it can generate randomized SOP points with a trigger output for synchronizing external devices. In the function generation mode, each polarization control axis can be selectively controlled with a sine, square, or triangle wave of user defined frequency and amplitude. Each polarization control axis can also be controlled manually, by setting the input voltage either from the front panel controls or through a PC interface. In externally triggered scrambling mode, completely random SOP’s are generated in response to synchronizing trigger signals, a feature desirable for recirculating loop applications. PolaMight™ puts the user in complete control.
