Low-threshold coherently-coupled organic VcsEL

Here we report observation of extremely low-threshold lasing in organic VCSELs when the excitons are coherently coupled non-radiatively to each other. Nonradiative coupling between excitons can enhance the emission cross-section of a gain material and lead to laser action at considerably lower excitation densities [1]. The coupling strength associated with the excitonic interaction is proportio...

Active coupled-resonator optical waveguides. I. Gain enhancement and noise

We use a tight-binding formalism in the time domain to analyze the effect of resonant gain enhancement and spontaneous emission noise in amplifying coupled-resonator optical waveguides (CROWs). We find the net amplification of a wave propagating in a CROW does not always vary with the group velocity, and depends strongly on the termination and excitation of these structures. The signal-to-noise...

Enhancement of optical processes in coupled plasmonic nanocavities [Invited].

We present detailed experimental and numerical investigations of resonances in deep nanogroove gratings in metallic substrates. These plasmonic nanocavity gratings feature enhanced fields within the grooves that enable a large enhancement of linear and nonlinear optical processes. This enhancement relies on both localized and propagating surface plasmons on the nanopatterned surface. We show th...

The golden ratio and aesthetics

Mario Livio is a scientist and self−proclaimed "art fanatic" who owns many hundreds of art books. Recently, he combined his passions for science and art in two popular books, The Accelerating Universe, which appeared in 2000, and The Golden Ratio, reviewed in this issue of Plus. The former book discusses "beauty" as an essential ingredient in fundamental theories of the universe. The latter dis...

Declustering Using Golden Ratio Sequences

In this paper we propose a new data declustering scheme for range queries. Our scheme is based on Golden Ratio Sequences (GRS), which have found applications in broadcast disks, hashing, packet routing, etc. We show by analysis and simulation that GRS is nearly the best possible scheme for 2-dimensional range queries. Speciically, it is the best possible scheme when the number of disks (M) is a...
