POLARIZATION INDEPENDENT ELECTRO-OPTICALLY INDUCED WAVEGUIDE

摘要

The invention provides an electro-optically induced waveguide including:
a waveguide layer stack having a core layer including an electro-optic material for guiding light waves; anda field generator for generating an electrical field in the core layer, wherein the field generator includes an electrode arrangement having a plurality of electrodes and a voltage supply arrangement for supplying at least two potentials to the electrode arrangement;wherein the field generator is configured to induce an electro-optic effect by the generated electrical field in a first cross sectional region of the core layer such that a propagation of transverse-electric polarized light waves is enabled in the first cross sectional region;wherein the field generator is configured to induce an electro-optic effect by the generated electrical field in a second cross sectional region of the core layer such that a propagation of transverse-magnetic polarized light waves is enabled in the second cross sectional region; andwherein the first cross sectional region and the second cross sectional region are overlapping in a cross sectional view.
