Abstract

The wavelength dependent optical parameters such as refractive index n and absorption coefficient α of porous silicon (PS) have been calculated from optical transmission spectra of plan-parallel films having different porosities. Since the effects of manufacturing conditions on film porosity and thickness have been investigated as well, a complete set of data is obtained enabling the design and easy realization of PS layers with certain structural and optical properties in advanced applications for optoelectronics and sensors.
