Dispersion and shape engineered plasmonic nanosensors

Hyeonho Jeong

Biosensors based on the localized surface plasmon resonance (LSPR) of individual metallic nanoparticles promise to deliver modular, low-cost sensing with high-detection thresholds. However, they continue to suffer from relatively low sensitivity and figure ...

Flat lensless phase imager

Christophe Moser, Manon Rostykus

Lensless imaging refers to an imaging technique which requires no imaging element between the light transmitted by the sample and the camera. This configuration enables designing compact devices. In the visible range, it is mainly investigated for microsco ...

Broadband electronically tunable reflection-based phase shifter for active-steering microwave reflectarray systems in Ku-band

This document provides the design of an electronically reconfigurable microwave phase shifter for reflectarray systems. The phase shifter is based on a hybrid coupler with reflective circuits in three ports. Each reflective circuit introduces a phase varia ...

High-power femtosecond Raman frequency shifter

Christoph Peter Hauri

We report on the generation of broadband, high-energy femtosecond pulses centered at 1.28 mu m by stimulated Raman scattering in a pressurized hydrogen cell. Stimulated Raman scattering is performed by two chirped and delayed pulses originating from a mult ...

Revisiting Newton’s rings with a plasmonic optical flat for high-accuracy surface inspection

Olivier Martin, Xiaolong Wang

Two parallel optical surfaces often exhibit colorful fringes along the lines of equal thickness because of the interference of light. This simple phenomenon allows one to observe subwavelength corrugations on a reflective surface by simply placing on it a ...

Negative plasmon dispersion in 2H-NbS2 beyond the charge-density-wave interpretation

Helmuth Berger

We examine the experimental and theoretical electron-energy loss spectra in 2H-Cu0.2NbS2 and find that the 1 eV plasmon in this material does not exhibit the regular positive quadratic plasmon dispersion that would be expected for a normal broad-parabolic- ...
