Unconventional photon blockade in doubly resonant microcavities with second-order nonlinearity

It is shown that noncentrosymmetric materials with bulk second-order nonlinear susceptibility can be used to generate strongly antibunched radiation at an arbitrary wavelength, solely determined by the resonant behavior of suitably engineered coupled micro ...

Femtosecond photoelectron and photoion spectrometer with vacuum ultraviolet probe pulses

Jakob Grilj

We describe a femtosecond photoelectron and photoion spectroscopy setup using a simple, novel way to produce a vacuum ultraviolet (VUV) probe pulse. We isolate the femtosecond VUV pulse from a high harmonic continuum by using the bandpass characteristics o ...

Linear response to harmonic forcing of the non-parallel Batchelor vortex

François Gallaire, Francesco Viola, Cristobal Manuel Arratia Martinez

The Batchelor vortex1 is a slowly developing asymptotic solution of the flow of a trailing line vortex. This flow has been comprehensively studied in its parallel approximation. In particular, the convective/absolute nature of the instability has been inve ...

Effects of surface plasmon polariton-mediated interactions on second harmonic generation from assemblies of pyramidal metallic nano-cavities

Elyahou Kapon, Benjamin Dwir, Justyna Szeszko

We use polarization-resolved two-photon microscopy to investigate second harmonic generation (SHG) from individual assemblies of site-controlled nano-pyramidal recess templates covered with silver films. We demonstrate the effect of the surface plasmon pol ...

How Important is Self-Consistency for the dDsC Density Dependent Dispersion Correction?

Eric Albert Georges Bremond, Nikolay Golubev

The treatment of dispersion interactions is ubiquitous but computationally demanding for seamless ab initio approaches. A highly popular and simple remedy consists in correcting for the missing interactions a posteriori by adding an attractive energy term ...

Rotor Design Optimization for a Reaction Sphere Actuator

Yves Perriard, Leopoldo Rossini

This paper presents the rotor design optimization for a reaction sphere (RS) actuator. The RS is a permanent-magnet synchronous spherical actuator whose rotor is magnetically levitated and can be accelerated about any desired axis. The RS is composed of an ...

Ultrasensitive Optical Shape Characterization of Gold Nanoantennas Using Second Harmonic Generation

Olivier Martin, Jérémy Butet, Krishnan Thyagarajan

Second harmonic generation from plasmonic nanoantennas is investigated numerically using a surface integral formulation for the calculation of both the fundamental and the second harmonic electric field. The comparison between a realistic and an idealized ...

Second-harmonic generation from periodic arrays of arbitrary shape plasmonic nanostructures: a surface integral approach

Olivier Martin, Jérémy Butet, Benjamin Gallinet, Krishnan Thyagarajan

A surface integral formulation for the second-harmonic generation (SHG) from periodic metallic-dielectric nano-structures is described. This method requires the discretization of the scatterers' surface in the unit cell only. All the physical quantities in ...

Power Compensation Approach and Double Frame Control for Grid Connected Converters

Alfred Rufer, Daniel Siemaszko

The handling of weak networks with asymmetric disturbances implies the accurate handling of the second harmonic component appearing under unbalanced networks. This paper proposes a two-step approach using classic vector control for operating the current co ...

Augmenting Second Harmonic Generation Using Fano Resonances in Plasmonic Systems

Olivier Martin, Jérémy Butet, Krishnan Thyagarajan

Significant augmentation of second harmonic generation using Fano resonances in plasmonic heptamers made of silver is theoretically and experimentally demonstrated. The geometry is engineered to simultaneously produce a Fano resonance at the fundamental wa ...
