CPC classification number: G02B6/12019 ,  G01J3/02 ,  G01J3/0205 ,  G01J3/0218 ,  G01J3/0264 ,  G01J3/1895 ,  G01J3/2803 ,  G01J3/36 ,  G01J3/44

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.
