Abstract

Using a molecular-quantum-electrodynamics method, we calculate the optical second-harmonic generation at the interface of two isotropic media caused by the multipolar contribution from the bulk. The most significant part of the radiation in both reflection and transmission is coherent, and the magnitude is generally comparable to that due to a monolayer of noncentrosymmetric molecules. This supports the previous treatments that started directly from Maxwell equations and a macroscopic-polarization-field formalism.
