【 摘 要 】

We propose an approach to control of polarization of propagating light in a waveguide geometry. We suggest using a three-waveguide coupler etched in a planar semiconductor microcavity with embedded quantum wells. The structure allows converting a linear polarization of polaritons, photons hybridized with quantum well excitons, excited by a resonant optical pump, to circular polarization, herewith opposite circularly-polarized components are spaced apart from each other in different waveguides. The mutual effect of the evanescent coupling of waveguides and the TE-TM splitting of guided modes are in the basis of the predicted effect.
