Polarization & Phase Control

All Fiber Piezoelectric Polarization Scrambler/Depolarizer

The AFPS series All-Fiber Optical Polarization Scramblers effectively randomize the polarization states of optical fibers while offering ultralow insertion loss, broad bandwidth, compatibility with all fiber types, and high power handling. This is achieved through precise, sequential stresses applied by four to six piezoelectric squeezing plates positioned at 45-degree angles, inducing birefringence phase retardation. The scrambler rapidly converts any input polarization into randomly distributed states across the entire Poincaré sphere and is bidirectional in operation. With squeezer frequencies up to 700 kHz and advanced digital circuitry, the device ensures uniform State of Polarization (SOP) distribution across a wide temperature range, making it ideal for demanding sensor applications.
