Abstract
A carbon dioxide (CO2) purity sensor package includes a fiber core, a periodic refractive index modulated fiber grating structure within the fiber core and a fiber cladding. A thermally conductive sensing layer is positioned about a portion of the fiber cladding surrounding the periodic refractive index modulated fiber grating structure. A gas chamber encloses the fiber cladding with the thermally conductive sensing layer.
