Polarization-Mode-Dispersion Compensation for Wideband Optical Signals

Summary: Researchers at Purdue University have developed a novel method that controls the polarization state of light and compensates PMD and PDL independently on a wavelength-by-wavelength basis.

Technology Benefits: Allows lightwave communication systems to run at higher speeds over longer distancesCapability to restore a single wavelength independent polarization state

*Abstract

*Background: Polarization mode dispersion (PMD), as well as other polarization effects, such as polarization dependent loss (PDL), has become a key factor that limits transmission rates and distances in high-speed fiber systems. Present technology allows polarization control and compensation of first-order PMD for a single wavelength. Current solutions do not apply to situations with wideband optical signals where the PMD varies across the optical bandwidth.
