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.
