A. Guerrero et Bs. Mendoza, MODEL FOR GREAT ENHANCEMENT OF 2ND-HARMONIC GENERATION IN QUANTUM DOTS, Journal of the Optical Society of America. B, Optical physics, 12(4), 1995, pp. 559-569
We present a model for second-harmonic generation in a two-dimensional
array of quantum dots. We show that the combined effect of the electr
omagnetic local field of the array and the intrinsic electronic resona
nces that arise from spatial confinement in the quantum dot produces g
reat enhancements of the second-order nonlinear susceptibilities, henc
e giving a high efficiency of second-harmonic generation.
