The PolaRite II is a fiber-squeezer-based polarization controller from General Photonics Corp. The company says it has no insertion loss, backreflection or polarization-dependent loss. Its response time is <35 µs, making it capable of tracking fast polarization variations. The company has reduced the device's activation-induced loss to <0.002 dB. It is suitable for signals ranging from 1280 to 1650 nm because of its wavelength independence. Half-wave voltage requirements have been reduced to <40 VDC, allowing the use of inexpensive electronics to drive and control the fiber squeezer controller. Applications include polarization-dependent-loss (PDL) compensation, mode-dispersion mitigation, dependent gain effect reduction, polarization stabilization and fast PDL measurement.
