Part of this work has been supported by the NRC Genome and Health Initiative.We present several new concepts to extend the capabilities of arrayed waveguide grating spectrometers. Strong lateral mode confinement wavegaide structure in the focal plane is used to increase resolution, a Michelson-type AWG spectrometer can improve optical throughput or etendue, and we show that AWG dispersion can be magnified many times by modifying the waveguide group index.engAdvanced concepts in waveguide spectrometersbook parthttp://dx.doi.org/10.1109/GROUP4.2006.1708228http://ieeexplore.ieee.orgopen access535Multi/DemultiplexerBirefringenceCompensationDevicesÓptica (Física)2209.19 Óptica Física
