Field-induced optical nonlinearity due to virtual transitions in semiconductor quantum well structures

Masamichi Yamanishi

A new concept on optical nonlinearity due to virtual transitions in quantum well structure with electric field, named virtual charge-induced optical nonlinearity, is proposed, with a showing of some examples of theoretical result on the nonlinearity. The switching time of the nonlinearity is expected to be extremely short, 100 fs. The nonlinearity seems to be observable and quite useful for the design of an ultrafast optical gate. A possibility of optical bistability without external optical feedback, based on the proposed nonlinearity, is pointed out.

Ultrafast optical nonlinearity by virtual charge polarization in DC-biased quantum well structures

M. Yamanishi, M. Kurosaki

An optical nonlinearity due to virtual charge polarization in a quantum-well structure biased by a DC electric field is proposed and discussed. The switching time of the nonlinearity is expected to be extremely short, on the order of 100 fs. An effective degenerative four-wave chi /sup 3/ parameter is estimated to be 1.0*10/sup -9/ (esu) for a graded gap AlGaAs quantum well and a detuning energy of pump light, 35 meV. The nonlinearity is observable and quite useful for designing an all-optical and ultrafast optical gate.>

Optical Nonlinearity Induced by Giant Dipole Moment of Wannier Excitons

Akira Shimizu

A new mechanism for enhancing optical nonlinearities in quantum well structures, subject to an electric field normal to the layers, is investigated. It is found that large nonlinearities are induced by virtual transitions of Wannier excitons with "giant dipole moments." In contrast to other mechanisms, this enhancement mechanism is independent of correlations between excitons, for any order of nonlinearities. This fact results in a resonant enhancement at half the excitonic energy, and an ultrafast response, even faster than other virtual-process-induced mechanisms.
