Enhanced Second Harmonic Generation in Plasmonic Nanocavities

Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh

We experimentally demonstrate significantly enhanced second harmonic generation using nanoengineered plasmonic nanocavities of core-shell structures (BaTiO3/Au). An enhancement factor of over 500 is measured in the second harmonic scattering efficiency com ...

Digital holographic microscopy investigation of second harmonic generated at a glass/air interface

Christian Depeursinge, Nicolas Pavillon, Jonas Kühn, Etienne Shaffer

Optical second harmonic generation, thanks to its coherent nature, is a suitable signal for interferometric measurements, such as digital holography: a well-established imaging technique that allows recovering complex diffraction wavefields from which it i ...

Instrument-independent specification of the diffraction geometry and polarization state of the incident X-ray beam

This work augments the proposal of Schwarzenbach & Flack [J. Appl. Cryst. (1989), 22, 601-605], who have advocated the use of a diffractometer-independent definition of the azimuthal angle

\psi

to specify the diffractiongeometry of a Bragg reflection. It ...

Harmonic holographic microscopy with circularly polarized excitation

Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh

We have developed a luminescent marker using the second harmonic generation (SHG) from noncentrosymmetric BaTiO3 nanocrystals. These nanoparticles are attractive due to their stable, non-saturating and coherent signal with a femtosecond-scale response time ...

Single molecule imaging of odorant receptors in supported planar lipid membranes

Theo Lasser, Marcel Leutenegger, Iwan Märki

Odorant receptors are an excellent example of natural superiority in binding specific small and hydrophobic molecules. Difficulties in expression, isolation and solubilisation of these receptors have been overcome recently by in vitro synthesis and incorpo ...

Lattice-matched GaN-InAlN waveguides at lambda=1.55 mu m grown by metal-organic vapor phase epitaxy

Nicolas Grandjean, Jean-François Carlin, Eric Feltin, Sylvain Nicolay, Mauro Mosca

We report on the demonstration of low-loss, single-mode GaN-InAlN ridge waveguides (WGs) at fiber-optics telecommunication wavelengths. The structure grown by metal-organic vapor phase epitaxy contains AlInN cladding layers lattice-matched to GaN. For slab ...

Micro-optical polarizer with high efficiency

Hans Peter Herzig, Toralf Scharf

Based on liquid crystal polymers (LCP) a compact micro-optical polarizer with high efficiency has been designed and realized. By using cylindrical mierolens arrays made of LCP and index matching layer, a complete separation of both polarization components ...

Excited excitonic states observed in semiconductor quantum dots using polarization resolved optical spectroscopy

Elyahou Kapon, Alok Rudra, Daniel Oberli, Valentina Troncale

We present results on the polarization-resolved photoluminescence emitted from InGaAs/AlGaAs single quantum dots (QDs) grown in inverted tetrahedral pyramids. The emitted light was detected for two mutually perpendicular linear polarization directions in t ...

On the complex three-dimensional amplitude point spread function of lenses and microscope objectives: theoretical aspects, simulations and measurements by digital holography

Christian Depeursinge, Tristan Colomb, Frédéric Montfort, Pierre Marquet, Jonas Kühn, Florian Charrière, Mihaela Marian

The point spread function is widely used to characterize the three-dimensional imaging capabilities of an optical system. Usually, attention is paid only to the intensity point spread function, whereas the phase point spread function is most often neglecte ...

Numerical aberrations compensation and polarization imaging in digital holographic microscopy

Tristan Colomb

In this thesis, we describe a method for the numerical reconstruction of the complete wavefront properties from a single digital hologram: the amplitude, the phase and the polarization state. For this purpose, we present the principle of digital holographi ...
