Ultrafast dynamic switching of optical response based on nonlinear hyperbolic metamaterial platform

Jiaye Wu, Qian Li

The pursuit of high-speed and on-chip optical communication systems has promoted extensive exploration of all-optical control of light-matter interactions via nonlinear optical processes. Here, we have numerically investigated the ultrafast dynamic switchi ...

Optica Publishing Group2022

In this thesis, we mainly utilize silver to construct the meta-atoms. Although suffering from easily oxidized, its excellent lossless property throughout the visible range makes it suitable for study. When preserved properly, silver-made metasurfaces can s ...

Investigation of photoinduced effects in plasmonic nanocavities

Aqeel Ahmed

Light matter interaction can be boosted by several orders of magnitude by tailoring the photonic environment, thus enabling a wide range of applications. One particular example are plasmonic nanostructures that support localized surface plasmon polariton ( ...

Highly efficient THz four-wave mixing in doped silicon

Gabriel Aeppli

Third-order non-linearities are important because they allow control over light pulses in ubiquitous high-quality centro-symmetric materials like silicon and silica. Degenerate four-wave mixing provides a direct measure of the third-order non-linear sheet ...

SPRINGERNATURE2021

Plasmonic nanostructures allow to controllably enhance linear and nonlinear light-matter interactions by concentrating the electromagnetic fields at the scales below the diffraction limit. This feature is highly desired for many applications, e.g. bio- and ...

Intrinsic luminescence blinking from plasmonic nanojunctions

Tobias Kippenberg, Christophe Marcel Georges Galland, Giulia Tagliabue, Magalí Alejandra Lingenfelder, Sachin Suresh Verlekar, Wen Chen, Karla Banjac, Aqeel Ahmed, Philippe Andreas Rölli

Plasmonic nanojunctions, consisting of adjacent metal structures with nanometre gaps, can support localised plasmon resonances that boost light matter interactions and concentrate electromagnetic fields at the nanoscale. In this regime, the optical respons ...

Light-Matter Interaction in III-Nitride Waveguides: Propagating Polaritons and Optical Gain

Joachim Armand Simonne Ciers

III-nitride waveguides featuring AlInN claddings and GaN/AlGaN quantum wells (QWs) offer promising perspectives for applications in many fields of short-wavelength photonics. Thanks to their nearly lattice-matched nature, these structures exhibit an excell ...

Subcycle Extreme Nonlinearities in GaP Induced by an Ultrastrong Terahertz Field

Christoph Peter Hauri, Mostafa Shalaby

We report on the experimental observation of extreme laser spectral broadening and a change in optical transmission in gallium phosphite induced by 25 MV/cm terahertz (THz) single-cycle internal field. Such intense THz radiation leads to twofold transient ...
