ABSTRACT
Spatially resolved photoluminescence (PL) spectra from tapered GaN nanowires (NWs) with triangular cross section exhibit marked intensity modulations along the NW length. The modulation periodicity is attributed to previously unrecognized, leaky transverse standing-waves that occur when the PL wavelength matches path length criteria. These Fabry–Perot modes can affect optical measurements in transparent nanostructures even for dimensions less than ∼λ/2n, where λ is the free-space wavelength and n is the index of refraction.

    ZnO nanostructures attract current interest because they have the potential to implement cavity quantum electrodynamics at room temperature. We report a photoluminescence mapping of ZnO nanobelts both at room temperature and 4.2 K. The multicavity modes were observed all over the belt surface,...

    Doppler wind lidar (DWL) measurements by the fringe-imaging technique in front of aircrafts at flight speed require rapid processing of backscattered signals. We discuss the measurement principle to derive the 3D wind vector from three line-of-sight (LOS) measurements. Then we simulate realistic...

    The superior etendu available from a Fabry-Perot spectrometer is also accessible when used in reflective mode in producing a narrow bandwidth rejection, or "notch," filter. We consider the instrumental defects and the practical effects involved in realizing a useful device. A simple figure of...

    Time-resolved optical measurements of probe reorientation in orthoterphenyl have been performed. Rotational correlation functions have been measured from 100 ps to 1 ms for anthracene and anthanthrene, while correlation functions were observed over a narrower time window for 9-phenylanthracene...

    The conductance of short ballistic wires with boundaries, whose curvature radius is comparable to the electron wavelength, is investigated. It is found that, in such wires, no conductance quantization takes place. Instead, pronounced interference effects are observed. These effects are related...

    We show that a metal can be turned into a broadband and omnidirectional absorber by coating a purely-dielectric thin layer of grating. An optimal design for such an absorber is proposed by putting a dielectric slot waveguide grating (SWG) on the metallic substrate. The SWG consists of two...

    A thin-film Fabry-Perot superconducting resonator is used to reveal the Little and Parks (LP) effect [Phys. Rev. Lett. 9, 9 (1962)], even at temperatures much lower than the critical temperature. A pair of parallel nanowires is incorporated into the resonator at the point of the supercurrent...

    Compact and efficient spectrometers are of great interest for biological and environmental sensing.
