The present work gives an overview of the developments in surface-enhanced Raman
scattering (SERS) with metal-coated porous silicon used as an active substrate. We focused …

The present state-of-the-art in understanding the mechanisms of the formation of porous
silicon (PS) and its physical properties is reviewed, with special emphasis on problems …

The relationship between the refractive index of porous silicon, its porosity and oxidation
degree has been calculated in the framework of the three-component Bruggeman effective …

Porous silicon (PS) samples obtained by dark etching of p+-type silicon wafers are oxidized
in dry air, at various temperatures from 200° C up to 800° C for 1− 20 h durations, to …

Since the first report on the use of porous silicon as an optical waveguide medium in 1995,
significant development has been made towards the understanding and applicability of such …

The introduction of solvents into the pores of optical waveguides formed using porous silicon
is shown to dramatically reduce the interfacial scattering loss of the waveguides (by as much …

The variation of the optical characteristics of thin films of oxidized porous silicon as a
function of the preparation regime and subsequent heat treatment is investigated by …

We study the use of polymer gratings as light couplers into porous silicon planar
waveguides for sensing applications. Experimental evidence of a guided mode in a grating …

The realisation of optical buried waveguides fabricated from porous silicon layers is
presented. The refractive index of porous silicon layer varies according to its porosity and its …

Porous silicon (PS) layers were fabricated by anodization of low resistive (highly doped) p-
type silicon in HF/ethanol solution, by varying current density, etching time and HF …
