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.

Application context

Why this design is used

Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.

Laboratory optical integration

All Fiber Piezoelectric Polarization Scrambler/Depolarizer: Laboratory optical integration depends on preserving the optical budget through the complete path. The 360 nm, 430 nm, 488 nm, 532 nm, 630 nm, 780 nm, 850 nm, 980 nm, 1060 nm, 1310 nm, 1550 nm, 2000 nm, 2.3-4.1 μm wavelength specification sets source and detector compatibility. The fiber/interface entry (SMF-28, HI1060, PM1550, PM1310, SM400, SM450, PM400, PM460, SM600, PM630, 780HP, PM780, SM800, PM850, PM980, Hi1060, SM1950, PM1950) must match the connected components.
