Two-photon-induced photoconductivity enhancement in semiconductor microcavities: a theoretical investigation
Folliot, H. and Lynch, Michael and Bradley, Ann Louise and Krug, T. and Dunbar, L.A. and Hegarty, J. and Donegan, John Francis and Barry, Liam P. (2002) Two-photon-induced photoconductivity enhancement in semiconductor microcavities: a theoretical investigation. Journal of the Optical Society of America B, 19 (10). pp. 2396-2402. ISSN 0740-3224 Full text available as: AbstractWe describe a detailed theoretical investigation of two-photon absorption photoconductivity in semiconductor microcavities. We show that high enhancement (by a factor of >10, 000) of the nonlinear response can be obtained as a result of the microcavity effect. We discuss in detail the design and performance (dynamic range, speed) of such a device with the help of the example of an AlGaAs/GaAs microcavity operating at 900 nm. This device shows promise for low-intensity, fast autocorrelation and demultiplexing applications. Download statistics
