Graphene surface plasmons at the near-infrared optical regime
Graphene surface plasmons near-infrared optical regime
2015/8/6
Graphene has been identified as an emerging horizon for a nanoscale photonic platform because the Fermi level of intrinsic graphene can be engineered to support surface plasmons (SPs). The current sol...
Near-infrared surface plasmon polariton dispersion control with hyperbolic metamaterials
Surface plasmons Metamaterials
2015/8/7
We demonstrate experimentally signatures and dispersion control of surface plasmon polaritons from 1 to 1.8 μm using periodic multilayer metallo-dielectric hyperbolic metamaterials. The fabricated str...
Method for Improving the Lateral Resolution of Near-Infrared (NIR) Single Optods: Application to Subcutaneous Vein Detection and Localization

2015/8/6
We demonstrate experimentally close to total absorption in monolayer graphene based on critical coupling with guided resonances in transfer printed photonic crystal Fano resonance filters at nea...
Near-infrared luminescence of rare earth ions in oxyfluoride lead borate glasses and transparent glass-ceramic materials
oxyfluoride glasses transparent glass-ceramics
2011/5/5
Oxyfluoride lead borate glasses singly doped with Nd3+ and Er3+ ions have been studied before and after thermal treatment. The orthorhombic PbF2 crystallites are formed during thermal treatment, which...
Air-bridged photonic crystal slabs at visible and near-infrared wavelengths
Air-bridged photonic crystal slabs visible near-infrared wavelengths
2015/8/11
Air-bridged photonic crystal slabs are demonstrated at visible and near-infrared wavelengths. We present experimental and theoretical studies of the transmission spectra of air-bridged photonic crysta...
