Phys. Rev. E 74, 066609 (2006) [4 pages]Broadband diffraction management and self-collimation of white light in photonic latticesReceived 21 July 2006; published 21 December 2006 We introduce periodic photonic structures where the strength of diffraction can be managed in a very broad frequency range. We show how to design arrays of curved waveguides where light beams experience wavelength-independent normal, anomalous, or zero diffraction. Our results suggest opportunities for efficient self-collimation, focusing, and reshaping of beams produced by white-light and supercontinuum sources. We also predict a possibility of multicolor Talbot effect, which is not possible in free space or conventional photonic lattices. © 2006 The American Physical Society URL:
