The PolarLok from Cambridge Research & Instrumentation Inc. actively transforms arbitrary input state-of-polarization (SOP) to a fixed linear output. The company says it is the first polarization controller that incorporates full SOP sensing, providing critical feedback for superior closed-loop control. Designed for use in the laboratory, this device is a suitable replacement for conventional, manually adjusted controllers. It measures Poincare coordinates in real time and provides continuous restoration of the polarization state.
