英文摘要	We study theoretically the effect of rashba spin-orbit interaction (rsoi) on the chiral splitting of quasi-two-dimensional quantum well (qw) exciton. by a nonvariational method, entire energy spectrum is treated simultaneously, it does not require a great deal of insight to choose a good variational function. we show that, the coexistence of electron and hole rsoi introduces a four-energy system for both heavy-hole and light-hole exciton, the competition between them leads to an anticrossing exciton energy spectrum. we also show that the chiral splitting of energy spectrum leads to a polarization-dependent optical absorption. the results suggest a way for direct optical measurements of rsoi parameters.
