Y. Dumeige et al., Enhancement of second-harmonic generation in a one-dimensional semiconductor photonic band gap, APPL PHYS L, 78(20), 2001, pp. 3021-3023
We demonstrate significant enhancement of second-order nonlinear interactio
ns in a one-dimensional semiconductor Bragg mirror operating as a photonic
band gap structure. The enhancement comes from a simultaneous availability
of a high density of states, thanks to high field localization, and the imp
rovement of effective coherent length near the photonic band edge. (C) 2001
