Abstract
An integrated broadband polarization controller is based on planar waveguide technology. The integrated broadband polarization controller emulates the polarization control function of an existing single channel polarization controller in a device that can be built in planar waveguide technology, and is expanded from single channel operation to broadband channel operation by designing the control degrees of freedom to be wavelength selectively addressable.
