Abstract
Elastic scattering of exciton polaritons in planar semiconductor microcavities has been used to create X-NOR logic gates. Polaritons with identical linear polarization scatter preferentially at the right angle and rotate their polarization by 90°.
On the other hand, scattering of polaritons having orthogonal linear polarizations is suppressed. We show that these effects are a consequence of the multiple scattering in microcavities which involve three and more polaritons.
The theory quantitatively reproduces the experimental data of C. Leyder et al., Phys.
