Abstract
ABSTRACT We review recent theoretical and experimental breakthroughs in the realm of slow and stopped light in structured photonic media featuring negative electromagnetic parameters (permittivity/permeability and/or refractive index). We explain how and why these structures can enable complete stopping of light even in the presence of disorder and , simultaneously, dissipative losses. Using full-wave numerical simulations we show that the incorporation of thin layers made of an active medium adj acently to the core layer of a negative-refrac tive-index waveguide can completely remove dissipative losses in a slow-light regime where the effective index of the guided wave is negative. We, also, review and compare several trapped rainbow schemes that have recently been proposed for slowing and stopping light. Keywords: Slow light, metamaterials, negative refractive index, plasmonics, waveguides, adiabatic variation 1. INTRODUCTION Metamaterials (MMs) 1-3 and slow light (SL) 4,5
