Abstract
We provide details on recent the characterization of arrayed-waveguide based Integrated Photonic Spectrograph chips, in particular the demonstration of simultaneous multiple input fibers that greatly increase its observational efficiency, and the three-fold increase in resolving power with slight modification of the chip structure. Further, we outline the setup that will be used in the first on-telescope prototype at the Anglo-Australian Telescope (AAT).
