The size of the optical elements (gratings, mirrors, lenses) in traditional astronomical spectrographs scales with telescope diameter (unless the instrument is operating at the diffraction limit).

The integrated photonic spectrograph offers the potential to break this scaling law and allow massively multiplexed...
