“…The SHG resonance at the MC mode is caused by the spatial confinement of the fundamental field inside the spacer and the constructive interference of complex SHG contributions from each PS layer which accounts for the phase-matching in the periodic MC structure. 19 The SHG enhancement at the PBG edges is due to the phase matching and the slight homogeneous fundamental field amplification inside MC. 6,7,19 Figure 3 shows the topographical and resonant SNOM images acquired at the MC cleavage.…”

Second-harmonic generation (SHG) spectra of single and coupled porous silicon-based photonic crystal microcavities are studied in both frequency and wave vector domains. For the fundamental field resonant to the microcavity mode the second-harmonic intensity is enhanced by 102 times in comparison with that outside the photonic band gap. SHG spectroscopy in identical microcavities coupled through the intermediate Bragg reflector reveals two SHG peaks if the fundamental field is in resonance with the splitted mode of coupled microcavities. The spatial confinement of the resonant fundamental radiation is directly probed at the microcavity cleavage by scanning near-field optical microscopy.

PACS 42.70.Qs, 81.07.Bc, 82.45.Vp For the first time, the sum-frequency generation (SFG) spectra of surface species have been measured in porous silicon (PS) layers. The range of the vibrations 2000 -2300 cm -1 for the native species Si-H x has been explored. Furthermore for the studied mesoporous materials, it has been found that, as opposed to the infrared absorption, the SFG signal increases with porosity. Finally, the angular dependence and the enhancement of the SFG signal were measured in a one-dimensional PS photonic crystal structure with a defect producing an energy level in the photonic band gap.

Sum frequency generation (SFG) involving an ultrafast infrared pulse and a 787 nm up‐conversion pulse mixed at the surface of planar or porous Si as well as planar GaAs has been studied. We demonstrate that SFG data can be obtained while porous silicon is in contact either with an aqueous solution or ethanol. The nonresonant SFG signal responds to the chemical composition of the interface. It is also found that ultrafast 787 nm pulses can induce photochemistry between hydrogen‐terminated porous silicon and either aqueous HCl, ethanoic HF, or ethanol. (© 2007 WILEY‐VCH Verlag GmbH & Co.
