TLDR
The results suggest opportunities for efficient self-collimation, focusing, and reshaping of beams produced by white-light and supercontinuum sources and predict a possibility of multicolor Talbot effect, which is not possible in free space or conventional photonic lattices.Abstract:
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.read more

Quantum-optical analogies using photonic structures
TL;DR: In this article, a review of recent theoretical and experimental advances in the field of quantum-optical analogies is presented, including some relevant optical analogies based on the use of curved photonic structures, including: coherent destruction of tunneling in driven bistable potentials, coherent population transfer and adiabatic passage in laser-driven multilevel atomic systems; quantum decay control and Zeno dynamics; electronic Bloch oscillations and Zener tunneling, Anderson localization and dynamic localization in crystalline potentials.

TL;DR: In this paper, the first-order effect of the broadening of a wavepacket can be suppressed as it propagates through a periodic potential, and higher-order effects are seen for the first time in an optical pulse guided along curved photonic lattices.
