Beyond the lateral resolution limit by phase imaging

Christian Depeursinge, Muhammed Fatih Toy, Yann Jérôme Michel Pascal Cotte

We present a theory stating how to overcome the classical Rayleigh-resolution limit. It is based upon a new resolution criterion in phase of coherent imaging process and its spatial resolution is thought to be only SNR limited. Recently, the experimental o ...

Network community-detection enhancement by proper weighting

Martin Hasler, Ali Ajdari Rad, Alireza Khadivi

In this article, we show how proper assignment of weights to the edges of a complex network can enhance the detection of communities and how it can circumvent the resolution limit and the extreme degeneracy problems associated with modularity. Our general ...

A starter kit for point-localization super-resolution imaging

Suliana Manley, Julia Gunzenhäuser

Super-resolution fluorescence imaging can be achieved through the localization of single molecules. By using suitable dyes, optical configurations, and software, it is possible to study a wide variety of biological systems. Here, we summarize the different ...

Advanced Brillouin-based distributed optical fibre sensors with sub-meter scale spatial resolution

Luc Thévenaz, Sang Hoon Chin, Nikolay Primerov, Kwang-Yong Song, Stella Foaleng Mafang

Classical configurations of Brillouin distributed optical fibre sensors show a spatial resolution limited by the phonon lifetime to 1 meter. Novel approaches can substantially overcome this limit through the prior activation of the acoustic wave. ...

Recent progress towards centimetric spatial resolution in distributed fibre sensing

Luc Thévenaz, Sang Hoon Chin, Nikolay Primerov, Kwang-Yong Song, Stella Foaleng Mafang

Optical fibre sensors based on stimulated Brillouin scattering have now clearly demonstrated their excellent capability for long-range distributed strain and temperature measurements. The fibre is used as sensing element and a value for temperature and/or ...

Nanoplasmonic Systems for Ultrasensitive Biomolecular Detection and Identification

Hatice Altug, Serap Aksu, Min Huang

Plasmonics, by localizing light below sub-diffraction limit and enhancing local field intensities, is enabling exciting possibilities in bio-detection field. In this talk, I will present novel plasmonic systems for ultrasensitive vibrational nanospectrosco ...

Analytical description of STED microscopy performance

Marcel Leutenegger

Stimulated emission depletion (STED) resolves fluorescent features that are closer than the far-field optical diffraction limit by applying a spatially modulated light field keeping all but one of these features dark consecutively. For estimating the effic ...

Opportunities in microstructured photonics

Hans Peter Herzig, Toralf Scharf, Tristan Sfez

The progress in novel light sources, detectors, materials and technology enable new opportunities and challenges for diffractive optics and nanoscale photonics. Important are also analysis tools, such as near-field imaging (SNOM). Only structures that can ...
