摘要：

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 1degrees/nm close to the principal band gaps, 10x more than equivalent gratings, and 100x more than equivalent prisms. Simple theories based on plane-wave models give excellent agreement with these results. (C) 2004 American Institute of Physics.
