Anomalous Selective Transparency of Many-Mode Surface-Corrugated Waveguides
We study the role of long-range correlations in random surface profiles for the transport through many-mode waveguides. It is found that the correlations that result in a perfect transmission for a single-mode case, lead to a quite unexpected phenomenon when the number of modes is large. Specifically, we show that these long-range correlations give rise to the appearance of non-interacting and ...
متن کاملZero-Mode-Waveguides Used in Cell and Surface Interactions
Zero-mode-waveguides (ZMWs) are subwavelength apertures on metal films. They are fabricated at the CNF with a lift-off process using electron-beam lithography (Figure 1). We further process these structures for biological studies by topping the surface with polyethylene glycol, and selectively coating the inside of the ZMWs with 2,4-dinitrophenyl (DNP) functionalized polymer. Using fluorescence...
متن کاملAttenuation coefficient of single-mode periodic waveguides.
It is widely accepted that, on ensemble average, the transmission T of guided modes decays exponentially with the waveguide length L due to small imperfections, leading to the important figure of merit defined as the attenuation-rate coefficient α=-⟨ln(T)⟩/L. In this Letter, we evidence that the exponential-damping law is not valid in general for periodic monomode waveguides, especially as the ...
متن کاملSpectral and mode properties of surface plasmon polariton waveguides studied by near-field excitation and leakage-mode radiation measurement
We present a method to couple surface plasmon polariton (SPP) guiding mode into dielectric-loaded SPP waveguide (DLSPPW) devices with spectral and mode selectivity. The method combined a transmission-mode near-field spectroscopy to excite the SPP mode and a leakage radiation optical microscope for direct visualization. By using a near-field fiber tip, incident photons with different wavelengths...
