Phoenix Photonics Ltd. has unveiled an eight-channel polarization controller based on its electronically variable all-fiber wave plates. It offers conventional manual polarization control as well as analog voltage control. Housed in a 19-in. rack format, it can be incorporated into standard test and measurement equipment. The device uses eight all-fiber polarization controllers, each consisting of three variable wave plates controlled by thermal variation of fiber birefringence. Knobs on the front panel provide manual control of the state of polarization in eight optical fibers simultaneously. And the instrument can be addressed with analog voltage inputs to each of the wave plates through a connector on the back plate.
