    Abstract: An infrared spectrometer for operation in the mid-infrared spectral range is presented, where the spectrometer includes a Bragg-mirror-based spectral filter that is operative for providing an interrogation signal whose spectral content is dispersed along a first direction at a filter aperture. The filter aperture is imaged through a sample by a thermal-imaging camera to create a focused image that is based on the interrogation signal and the absorption characteristics of the sample. As a result, embodiments in accordance with the present disclosure can be smaller, less complex, and less expensive than infrared spectrometers known in the prior art.

    Abstract: A Fabry-Perot cavity-based spectral notch filter is disclosed, where the filter is operative for providing an output optical signal whose spectral content is spatially dispersed along at least one direction, while also controlling the spectral position and spectral range of the output light. In some embodiments, the spectral filter is integrated with a detector arrays to realize a compact, high-resolution spectrometer that can rapidly acquire the absorption spectrum of a sample with high sensitivity.

    Abstract: A method of etching active quantum nanostructures provides the step of laterally etching of an intermediate active quantum nanostructure layer interposed between cladding layers. The lateral etching can be carried out on at least one side of the intermediate active quantum nanostructure layer selectively, with respect to the cladding layers to define at least one lateral recess or spacing in the intermediate active quantum nanostructure layer and respective lateral protrusions of cladding layers protruding with respect to the intermediate active quantum nanostructure layer. This method can be applied to create devices including active quantum nanostructures such as, for example, three-dimensional photonic crystals, a photonic crystal double-slab and a photonic crystal laser.
