High Speed Polarisation Controller

The Lightwaves2020’s high-speed polarisation controller (PC) is based on novel optical material offering fast response in ms, in contrast with conventional polarisation controllers with speed in ms. The dramatic increase in response speed enables the new polarisation controller suitable for demanding 40Gbs PMDC application as well as polarisation Mux / DeMux. In addition, the new high-speed polarisation controller is ideal for fibre sensing in optical security, spectroscopy and polarisation dependent imaging in biomedical applications.  An optional driver-PCB, on which the polarisation controller is mounted, is provided. The device is driven by 0-5VDC voltage to produce 0 - p phase retardation of polarisation state. The high-speed polarisation controller (PC) has options of three or four cell design. The fourth cell is added for faster searching and controlling.Features
