In the present work, we introduce the anodic growth of conical shaped TiO2 nanotube arrays. These titania nanocones provide a scaffold for dye-sensitized solar cell (DSSC) structures with significantly improved photon management, providing an optimiz

Plasmonic metasurfaces are investigated that consist of a sub wavelength line pattern in an ultrathin (~ 10 nm) silver film, designed for extraordinarily suppressed transmission (EOST) in the visible spectral range. Measurements with a near-field sca

We experimentally demonstrate spectrally broad (λ 0 =1200–1800 nm) in-plane negative diffraction of SPPs in an array of plasmonic channel waveguides with negative mutual coupling resulting in negative refraction on the array's interface and refocu

We experimentally demonstrate wave propagation in 2D nanophotonic epsilon-near-zero (ENZ) waveguides. We show an ENZ double-slit experiment, investigate ENZ diffraction and observe the disappearance of wavelength-scale obstacles close to the cut-off

We experimentally demonstrate an ultracompact PlasMOStor, a plasmon slot waveguide field-effect modulator based on a transparent conducting oxide active region. By electrically modulating the conducting oxide material deposited into the gaps of highl

High quality CdS nanowires suspended in air were optically pumped both below and above the lasing threshold. The polarization of the pump laser was varied while emission out of the end facet of the nanowire was monitored in a ‘head-on’ measuremen

We demonstrate experimentally and numerically that in fiber tips as they are used in NSOMs azimuthally polarized electrical fields (|E(azi)|2 / |E(tot)|2 ≈55% ± 5% for λ0 = 1550 nm), respectively subwavelength confined (FWHM ≈450 nm ≈λ0/3.5)

Using a near-field scanning optical microscope we investigate the optical response of a plasmonic metasurface consisting of a sub-wavelength periodic pattern in an ultrathin (10nm) silver film, which shows extraordinarily suppressed transmission in t

We experimentally demonstrate plasmonic nano-circuits operating as sub-diffraction directional couplers optically excited with high efficiency from free-space using optical Yagi-Uda style antennas at \lambda = 1550 nm. The optical Yagi-Uda style ante

In near field scanning optical microscopy (NSOM) a sharp tip with a defined aperture allows for direct scanning and subwavelength imaging of samples that otherwise cannot be excited from the far field. To control the interaction between tip and sampl
