  • ULTRA-WIDE BAND SLOW LIGHT STRUCTURE USING PLASMONIC GRADED GRATING STRUCTURES
    Publication number: 20100110525
    Abstract: A slow light system includes a substrate and a metal layer formed thereon, the metal layer having a graded grating structure formed at a surface thereof, wherein the grating depth of the grating structure is sized such that surface-plasmon polariton dispersion behavior of the grating structure differs at different respective locations along the grating structure. Different wavelengths of incident light waves can be slowed at the respective locations along the grating structure.
