Two-photon imaging through a multimode fiber

Demetri Psaltis, Christophe Moser, Edgar Emilio Morales Delgado

In this work we demonstrate 3D imaging using two-photon excitation through a 20 cm long multimode optical fiber (MMF) of 350 mu m diameter. The imaging principle is similar to single photon fluorescence through a MMF, except that a focused femtosecond puls ...

A new strategy for improving fluorescent immunoassays using photonic crystals

Hans Peter Herzig, Elsie Barakat

The most widely used substrates for fluorescent immunoassay are based on transparent materials such as glass or plastic with almost no optical functionality. Very recently, optical nanostructures made of metal on dielectrics have been proposed to perform p ...

Optical spectroscopy of the bladder washout fluid to optimize fluorescence cystoscopy with Hexvix

Hubert van den Bergh, Georges Wagnières, Matthieu Philippe Emmanuel Zellweger, Blaise Lovisa, Carla Martoccia

Fluorescence cystoscopy enhances detection of early bladder cancer. Water used to inflate the bladder during the procedure rapidly contains urine, which may contain fluorochromes. This frequently degrades fluorescence images. Samples of bladder washout flu ...

Large-scale sub-100 nm compound plasmonic grating arrays to control the interaction between localized and propagating plasmons

Olivier Martin, Thomas Gerd Siegfried, Arash Farhang

Compound plasmonic resonances arise due to the interaction between discrete and continuous metallic nanostructures. Such combined nanostructures provide a versatility and tunability beyond that of most other metallic nanostructures. In order to observe suc ...

Enhancement of Second Harmonic Signal in Nanofabricated Cones

Aleksandra Radenovic, Andrea Lovera, Oriol López Sánchez, Fabrizia Dutto, Martin Heiss

Geometrical effects in optical nanostructures on nanoscale can lead to interesting phenomena such as inhibition of spontaneous emission,(1,2) high-reflecting omnidirectional mirrors, structures that exhibit low-loss-waveguiding,(3) and light confinement.(4 ...

Use of red autofluorescence for monitoring prodiginine biosynthesis

Paul Guichard

Prodigiosin-like pigments or prodiginines (PdGs) are promising drugs owing to their reported antitumor, antibiotic, and immunosuppressive activities. These natural compounds are produced by several bacteria, including Streptomyces coelicolor and Serratia m ...

Surface nanophotonics with Bloch waves on dielectric multilayers

Olivier Martin, Hans Peter Herzig, Andrea Lovera, Tristan Sfez, Francesco Michelotti

Planar mutilayers sustaining either TE or TM polarized Bloch Surface Waves (BSWs) offer new opportunities for management of light at the nanoscale. We will discuss how BSWs can be exploited in guiding and confining light on nanometric relieves, enhancing f ...

Fano Resonances in Plasmonic Nanostructures

Benjamin Gallinet

Surface plasmons are able to generate extremely strong and confined optical fields at a deep-subwavelength scale, far beyond the diffraction limit, and now play a central role in nanosciences. A proper combination of plasmonic nanostructures can support Fa ...
