Paper Abstract

Size effects in optical second harmonic generation (SHG) from Si(001)-SiO2 planar micro-cavity structures are studied for fundamental wavelengths from 700 nm to 850 nm. The observed dependence of SHG intensity on the thickness of oxide layer is explained, in part, by an optical Casimir nonlocality arising from interference of zero-point fluctuations in micro-cavity, which is distinguished from microscopic interface effects. Detailed theoretical analysis of the Casimir nonlocal contribution to the quadratic susceptibility using a diagrammatic technique is performed for visible and IR regions. The difference in the length scale of the Casimir contribution at 800 nm and 1064 nm fundamental wavelength is discussed.
