Resonant second harmonic generation by a semiconductor quantum well in electric field

Abstract

Both single- and double-resonance operating regimes are analyzed, and the latter is found to enable very high conversion efficiencies of pump to harmonic if accompanied by quasiphase matching by periodic alternation of the field direction. The self-consistent procedure of level energies and wave function calculation is also described.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
