Abstract
An electro-optic waveguide polarization modulator () comprising a waveguide core () having first and second faces defining a waveguide core plane, a plurality of primary electrodes () arranged at a first side of the waveguide core plane and out of said plane, and at least one secondary electrode () arranged at a second side of the waveguide core plane and out of said plane, wherein the electrodes () are adapted in use to provide an electric field having field components () in two substantially perpendicular directions within the waveguide core () so as modulate the refractive index thereof such that electromagnetic radiation propagating through the core () is converted from a first polarization state to a second polarization state.
