a Schematic of the measurement setup. The sample is illuminated by a tuneable light source, and the deflected beam is imaged on a camera. b Deflection angles for the control, achromatic, positive-dispersion, and superchromatic beam deflectors as functions of wavelength. The solid curves represent the simulated responses. c Deflection efficiencies of the beam deflectors as functions of wavelength. The solid lines serve as guides for the eye. The power measurements were obtained at the locations indicated in a.
