Abstract
There is described an infrared spectrometer having an optical circuit which comprises one or more hollow waveguides provided by elongate channels formed in a substrate. The optical circuit is arranged such that infrared light in the optical circuit acquires one or more spectral properties for detection by the spectrometer. A laser source couples laser light into an input hollow waveguide portion of the optical circuit, and an optical detector receives the light from an output hollow waveguide portion of the optical circuit, so that an analyser can determine said one or more spectral properties from the detected light.
