Stopping and Time Reversal of Light in Dynamic Photonic Structures via Bloch Oscillations
Stefano Longhi
It is theoretically shown that storage and time-reversal of light pulses can be achieved in a coupled-resonator optical waveguide by dynamic tuning of the cavity resonances without…
Wide-band optical field concentrator for low-index core propagation
D. de Ceglia, M. De Sario, A. D'Orazio +4
We propose a novel chirped structure consisting of a low index polymer core bounded by modulated multilayer claddings, to realize an optical field concentrator with virtually zero…
Optical Zener-Bloch oscillations in binary waveguide arrays
Stefano Longhi
Zener tunneling in a binary array of coupled optical waveguides with transverse index gradient is shown to produce a sequence of regular or irregular beam splitting and beam recomb…
Gap solitons in metamaterials
Stefano Longhi
Electromagnetic localization and existence of gap solitons in nonlinear metamaterials, which exhibit a stop band in their linear spectral response, is theoretically investigated. F…
