Abstract
A spectrometer may include a rotated volume Bragg grating (r-VBG) within a volume of a material having an input face, where the r-VBG reflects portions of input light propagating through the input face that satisfies a Bragg condition for wavelengths within a spectral band, where a period of the r-VBG along the grating vector is chirped to vary along the grating vector to provide that the Bragg condition is satisfied for different wavelengths at different depths, and where a spectrum of the input light is spatially resolved in the reflected portions of the input light by the r-VBG. The spectrometer may further include a multi-pixel detector configured to receive the reflected portions of the input light from the r-VBG, where the multi-pixel detector is configured to output spectral data indicative of the spectrum of the input light within the spectral band.
