| 摘要 |
The invention uses the optical nonlinearity of electrically biased exciton polariton in a strong coupling regime or exciton polariton in a strong coupling regime with spatially separated electron and hole pairs. The method comprises providing a signal light (1300) to an exciton polariton system in a strong coupling regime and excitons with spatially separated electron and hole pairs, providing a control light (1302) to the exciton polariton system and removing the control light (1302). Various applications are available, including optical turnstiles, all-optical switches, all-optical phase retardation, low-power saturable transmitters and mirrors. In addition, the applications may operate at single- or few-photon levels. |
