We demonstrate the fabrication of superprism devices in photonic crystal waveguides with excellent
transmission through 600 rows of 160 nm diameter holes. Broadband spectral and angular
measurements allow mapping of the chromatic refractivity. This shows the ability of such devices
to super-refract by more than 1° /nm close to the principal band gaps, 10 more than equivalent
gratings, and 100 more than equivalent prisms. Simple theories based on plane-wave models give
excellent agreement with these results.
