We theoretically treat the Sagnac effect of excitonic polaritons in bulk material and microcavity. Using the coupling between the electromagnetic and excitonic waves, the rotational sensitivity per unit area of a Sagnac loop can be tuned from light to exciton behavior by varying frequency. We also discuss the feasibility and the difficulties of the hybrid light-exciton wave Sagnac interferometer. We show that the quasi-two-dimensional microcavity excitonic polariton is a better candidate than the bulk one. Considering the short decoherence time in semiconductors, we suggest using the degenerate four-wave mixing of the microcavity excitonic polaritons to generate two intrinsically coherent conjugate waves.http://gateway.webofknowledge.com/ga...
