Abstract

Transitions between the subbands of quantum wells have extremely large oscillator strengths which are currently used in novel IR detectors.1,2 Since second-order nonlinear coefficients are proportional to the square of the oscillator strength, strong nonlinear effects are also expected in such systems provided that inversion symmetry is broken.
