POLARIZATION INDEPENDENT ELECTRO-OPTICALLY INDUCED WAVEGUIDE

摘要

The invention provides an electro-optically induced waveguide comprising: a waveguide layer stack (100, 101, 102) having a core layer (100) comprising an electro-optic material for guiding light waves; and a field generator for generating an electrical field (EF) in the core layer (100), wherein the field generator comprises an electrode arrangement (20-28) having a plurality of electrodes (201-217) and a voltage supply arrangement (30) for supplying at least two potentials (U0, U1, U2) to the electrode arrangement (20-28); wherein the field generator is configured to induce an electro-optic effect by the generated electrical field (EF) in a first cross sectional region (CR1) of the core layer (100) such that a propagation of transverse-electric polarized light waves is enabled in the first cross sectional region (CR1); wherein the field generator is configured to induce an electro-optic effect by the generated electrical field (EF) in a second cross sectional region (CR2) of the core layer (100) such that a propagation of transverse-magnetic polarized light waves is enabled in the second cross sectional region (CR2); and wherein the first cross sectional region (CR1) and the second cross sectional region (CR2) are overlapping in a cross sectional view.
