Tailoring and cancelling dispersion of slow or stopped and subwavelength surface-plasmonodielectric-polaritonic light

Abstract

A new physical mechanism enabling simultaneous cancellation of group-velocity and attenuation dispersion to extremely high orders for subwavelength light of any small positive, negative or zero value of the group velocity is introduced. It exploits the unique dispersive properties of the surface polaritons supported by a novel proposed material platform of multilayered Surface-PlasmonoDielectric-Polaritonic (SPDP) systems. These single-polarization broadband-slow- or stopped-light systems are thus essentially free from all kinds of dispersion and could therefore have great impact on the technology of integrated nanophotonics, for example in the design of efficient and very compact delay lines and active devices. The same dispersion-manipulation mechanism can be employed to invent a large variety of exotic slow-light dispersion relations.
