The unique optical properties of porous silicon show it to be a promising material for imaging and spectroscopy in the mid-infrared and long-infrared wavelength ranges. A tunable MEMS filter using porous silicon as a high-reflectivity layer is proposed. Measurements on fabricated porous silicon-based distributed Bragg reflectors and Fabry-Perot etalons are presented.
