Chalcogenide circuits for the realization of CO2 micro-sensors operating at 4.23 µm

In a context where the control of gases becomes important in a wide range of applications - health care, industry, housing, transportation, environment - we have in sight the realization of infrared optical micro-sensors. In particular, we wish to develop an optical micro-sensor operating at the wavelength 4.23 µm, wavelength corresponding to an absorption band of carbon dioxide, the main greenhouse gas.
