This book shows how dispersion engineering in two dimensional dielectric photonic crystals can provide new effects for the precise control of light propagation for integrated nanophotonics. Dispersion engineering in regular and graded photonic crystals to promote anomalous refraction effects is studied from the concepts to experimental demonstration via nanofabrication considerations.

This book shows how dispersion engineering in two dimensional dielectric photonic crystals can provide new effects for the precise control of light propagation for integrated nanophotonics. Dispersion engineering in regular and graded photonic crystals to promote anomalous refraction effects is studied from the concepts to experimental demonstration via nanofabrication considerations. Self collimation, ultra and negative refraction, second harmonic generation, mirage and invisibility effects which lead to an unprecedented control of light propagation at the (sub-)wavelength scale for the field of integrated nanophotonics are detailed and commented upon.Hinweis: Dieser Artikel kann nur an eine deutsche Lieferadresse ausgeliefert werden.
Olivier Vanbésien is Professor at the University of Lille and a researcher at IEMN (Institute of Electronics, Micro-electronics and Nanotechnology) in Villeneuve d'Ascq, France. He is the author of Artificial Materials, published in 2012, has authored and co-authored 70 papers in international journals and has presented 40 papers at international conferences. His current research field concerns the development of photonic crystal or metamaterial-based flat lenses for operation at 1.55m. Emmanuel Centeno is Professor at Blaise Pascal University in Clermont-Ferrand, France. His research fields cover electromagnetic theory and simulations of photonic crystals and metamaterials. He has recently developed new concepts of graded photonic crystals and second harmonic metamaterial flat lenses.
