Abstract
Cost effective multi-wavelength light sources are key enablers for spectroscopic applications at Mid-IR wavelength range. Use of interference filters is the most conventional method for selecting IR absorption bands for gas sensing. Currently, MEMS based tuneable filters are also available for required Mid-IR wavelengths. Integrated optics based filters are the most advanced method for spectral filtering. We introduce a novel Mid-IR light source concept that is utilizing a novel Si-photonics based Photonic Integrated Circuit (PIC) filter and wide-band Mid-IR SLEDs. The spectral bands are switchable and tunable and they can be modulated. The source allows for the fabrication of an affordable multi-band gas sensor with good selectivity and sensitivity. The unit price can be lowered in high volumes by utilizing tailored molded IR lens technology and automated packaging and assembling technologies.
