Stark effect induced microcavity polariton solitons

This paper proposes a way of generating polariton solitons (PSs) in semiconductor microcavity using Stark effect as the trigger mechanism. A Stark pulse performing as the writing beam is used to excite non-resonant fluctuations of polariton, which finally evolves into bright PSs. It is found that polarization of the generated PS is independent on the writing beam, and a branch of PS solutions versus pump parameters could be found through optimizing parameters of the Stark pulse, while the polarization of PS depends greatly on the writing beam when coherent excitation method is used.
