Abstract
We describe theoretical analysis and design of one-dimensional photonic crystal prisms. We find that inside the photonic crystal, for frequencies near the band edges, light propagation direction is extremely sensitive to the variations in wavelength and incident angle. Outside the photonic crystal, propagation direction of transmitted light is highly sensitive to changes in wavelength, but less so to incident angle. For transmitted light outside the photonic crystal, the superprism effect can be used for wavelength dispersion over entire photonic bands, rather than just near the band edges only. This extended-range superprism effect broadens the useful wavelength rage, admits better optical transmission, and exhibits angular dependence on wavelength with greatly reduced non-linearity.
