Generation of Rabi-frequency radiation using exciton-polaritons
Generation of Rabi-frequency radiation using exciton-polaritons
We study the use of exciton-polaritons in semiconductor microcavities to generate radiation spanning the infrared to terahertz regions of the spectrum by exploiting transitions between upper and lower polariton branches. The process, which is analogous to difference-frequency generation (DFG), relies on the use of semiconductors with a nonvanishing second-order susceptibility. …
