Applications
Polarization control and scrambling, averaging PDL effects, PMD/PDL tests and compensation of external temperature/stress changes. Polarization scrambling or control; polarization stabilization; mitigation of polarization mode dispersion (PMD) and polarization-dependent loss (PDL); PDL and PMD measurement systems; interferometers and sensors.
Key Features
The described four-channel arrangement uses four DC drive channels varying over+/-5V. A5V drive produces squeezing action>25N for360° polarization variation. Three neighboring squeezers have45° relative offsets; the fourth compensates in real time to avoid resetting at control limits. Response>100Hz compensates temperature and stress. Three-channel systems suit scrambling/averaging and PDL measurements; four-channel systems support continuous reset-free control. No special drive circuitry, internal voltage amplifier or high-voltage signal is required. Negligible insertion loss, back reflection, and polarization-dependent loss; response speed >100Hz; continuously controllable polarization state; low-voltage drive.
