Impact of feature-size dependent etching on the optical properties of photonic crystal devices

Romuald Houdré, Rolando Ferrini

Feature size dependence in Ar/Cl2 chemically assisted ion beam etching of InP-based photonic crystals (PhCs) and its influence on the optical properties of PhC devices operating in the band gap are investigated. The analysis of the measured quality factors ...

Getting cited: does open access help?

Patrick Gaulé

We reexamine the widely held belief that free availability of scientific articles increases the number of citations they receive. Since open access is relatively more attractive to authors of higher quality papers, regressing citations on open access and o ...

Multiframe SURE-LET denoising of timelapse fluorescence microscopy images

Michaël Unser, Saskia Joëlle Delpretti Anex, Thierry Blu, Florian Luisier, Sathish Ramani

Due to the random nature of photon emission and the various internal noise sources of the detectors, real timelapse fluorescence microscopy images are usually modeled as the sum of a Poisson process plus some Gaussian white noise. In this paper, we propose ...
