Tm. Benson et al., Progress towards achieving integrated circuit functionality using porous silicon optoelectronic components, MAT SCI E B, 69, 2000, pp. 92-99
Porous silicon offers many potential advantages for the realisation of opto
electronic circuits and systems. This paper assesses some of the technologi
es available for the fabrication of porous silicon waveguides for visible a
nd infrared applications. The unique physical and chemical properties of th
e material enable additional functionality over other silicon-based optoele
ctronic technologies. As an example, optical sensing of solvents and vapour
s is discussed using both optical waveguides and multi-layer reflector stac
