Abstract
A spectrometer includes a one or more Arrayed Waveguide Gratings (AWGs), which have output waveguides which are non-uniformly spaced at the output slab and/or with different passband widths. AWGs can be cascaded, each receiving a different portion of the spectrum passing through an upstream AWG, for further processing and/or detection.
