摘要

Porous Germanium (PGe) is a very promising material for spectroscopy and detection applications in the mid-IR wavelength range, due to its particular physicochemical properties, in particular, its large spectral transparency window ranging from 2 to 15 μm. Multilayers, such as Bragg reflectors and microcavities, based on porous germanium material are designed and their optical spectra are simulated to detect CO 2 and CH 4 .
