We propose and experimentally demonstrate a 40Gbps downstream TD-VSB-IMDD OFDM PON scheme with symbol pre-distortion that greatly reduces the computational complexity of ONUs. 1.4dB and 2.3dB sensitivity improvement are demonstrated over 60km and 100km transmission.
We demonstrate a prototype 3D plasmon ruler based on coupled plasmonic oligomers in combination with high-resolution plasmon spectroscopy, rendering the retrieval of the complete spatial configuration of complex macromolecular and their dynamic evolution possible.
We demonstrate antenna-enhanced hydrogen sensing at the single-particle level. We place a single palladium nanoparticle near the tip region of a gold nanoantenna and detect the changing optical properties of the system upon hydrogen exposure.
In this contribution, we are going to present two plasmonic concepts for hydrogen sensing. Our first concept is based on metallic photonic crystals, where a gold grating together with a thin layer of Pd in combination with a waveguide of WO3 can give a strong resonance in the extinction or reflection spectrum. Upon hydrogen exposure, the WO3 undergoes a refractive index change, which will shift the...
Summary form only given. We introduce a novel sensor concept in the field of plasmonics, namely plasmon-induced transparency sensors. These sensors combine localized particle plasmon resonances with extremely small sensing volume with excellent sharp spectral resonances that show a good response to refractive index changes of the surrounding environment. The principle is based on the plasmonic analog...
We experimentally demonstrate a nanoplasmonic analog of electromagnetically induced transparency utilizing a stacked optical metamaterial. Specifically, we achieve a very narrow transparency window with high modulation depth due to nearly complete suppression of radiative losses.
