Polaritonic Cross Feshbach Resonance

Daniel Oberli, Marcia Portella Oberli, Mitchell David Anderson, Naotomo Takemura, Morteza Navadeh Toupchi

We demonstrate the existence of a cross Feshbach resonance by strongly driving a lower polariton mode and by monitoring in time the transmission of a short optical pulse at the energy of the upper polariton mode in a semiconductor microcavity. From the sig ...

Improved off‐resonance phase behavior using a phase‐inverted adiabatic half‐passage pulse for 13 C MRS in humans at 7 T

Rolf Gruetter, Lijing Xin, Daniel Gallichan, Eulalia Serés Roig

In vivo (13) C MRS at high field benefits from an improved SNR and spectral resolution especially when using surface coils in combination with adiabatic pulses, such as the adiabatic half-passage (AHP) pulse for (13) C excitation. However, the excitation p ...

Label-free plasmonic biosensors for real-time live cell analysis

Xiaokang Li

For decades, the understanding of life has been focused on its most fundamental building blocks: molecules. Deciphering the dynamic activities of protein molecules in human cells is of vital significance for fundamental and clinical studies. The minuscule ...

Bloch surface waves at the telecommunication wavelength with lithium niobate as the top layer for integrated optics

Hans Peter Herzig, Myun Sik Kim, Maria-Pilar Bernal

Lithium niobate (LN)-based devices are widely used in integrated and nonlinear optics. This material is robust and resistive to high temperatures, which makes the LN-based devices stable, but challenging to fabricate. In this work, we report on the design, ...

High Spectral Resolution Plasmonic Color Filters with Subwavelength Dimensions

Giulia Tagliabue

Rapid advances in image sensor technology have generated a mismatch between the small size of image sensor pixels and the achievable filter spectral resolution. This mismatch has prevented the realization of chip-based image sensors with simultaneously hig ...

Quantitative robustness analysis of topological edge modes in C6 and valley-Hall metamaterial waveguides

Romain Christophe Rémy Fleury, Bakhtiyar Orazbayev

Recent advances in designing time-reversal-invariant photonic topological insulators have been extended down to the deep subwavelength scale, by employing synthetic photonic matter made of dense periodic arrangements of subwavelength resonant scatterers. I ...

The interfacial structure of nano-and micron-sized oil and water droplets stabilized with SDS and Span80

Sylvie Roke, Esther Amstad, Nikolay Smolentsev, Evangelia Zdrali, Gianluca Nicolas Etienne

In this work, we provide a comparison between the stability and the interfacial structure of micrometer-sized and nanometer-sized droplets by employing a multi-instrumental approach comprised of the surface-sensitive technique of sum frequency scattering a ...

Bistable silicon photonic MEMS switches

We present the design of a non-volatile, bistable silicon photonic MEMS switch. The switch architecture builds on our previously demonstrated silicon photonic MEMS switch unit cell, using vertically movable adiabatic couplers. We here propose to exploit co ...

Optical properties of size selected neutral Ag clusters: electronic shell structures and the surface plasmon resonance

Harald Brune, Wolfgang Harbich, Chongqi Yu

We present optical absorption spectra from the ultraviolet to the visible for size selected neutral Ag-n clusters (n = 5-120) embedded in solid Ne. We compare the spectra to time-dependent density functional calculations (TDDFT) that address the influence ...
