Russian Quantum Center, Novaya 100, 143025 Skolkovo, Moscow Region, Russia(Dated: December5,2014)We show theoretically that a weakly interacting gas of spin-polarized exciton-polaritons in asemiconductormicrocavitysupportspropagationofspinwaves. Thespinwavesarecharacterisedbyaparabolicdispersionatsmallwavevectorswhichisgovernedbythepolariton-polaritoninteractionconstant. Due to spin-anisotropy of polariton-polariton interactions the dispersion of spin wavesdepends on the orientation of the…
