OZ Optics' EOPC high-speed electro-optic polarization controller is based on a novel, low-loss, high-speed, free-space electro-optic crystal technology. It provides a simple, efficient means to quickly manipulate the state of polarization by applying an external voltage. High-speed polarization state management is enabled using two to four crystals in a row with remarkably low loss, all housed in a compact and robust butterfly package.

The device can be offered with 2, 3 or 4 crystals (depending on the customer’s requirement), and by applying external voltages one can change/manipulate/control the output polarization state. For endless polarization control, a device with 4 crystal elements is required, while a 3-elements device will be sufficient for polarization scrambling mode operation.

The compact, motionless, and vibration-free design allows fast linear response with less than 10 μs response time to the control signal. The controller's rapid response speed easily handles changes in polarization, caused by the external environment, and is highly suitable for polarization controlling and scrambling to either average PDL and PDG effects, or for making PMD, PDL or DOP measurements. This makes the EOPC device ideal for precise test and measurement applications.
