Single-photon emitters with stable and uniform photoluminescence properties are important for quantum technology. However, in many cases, colour centres in diamond exhibit spectral diffusion and photoluminescence intensity fluctuation. It is therefore essential to investigate the dynamics of colour centres at the single defect level in order to enable the on-demand manipulation and improved app...
We consider the statistical analysis of random sections of a spin fibre bundle over the sphere. These may be thought of as random fields that at each point p ∈ S2 take as a value a curve (e.g. an ellipse) living in the tangent plane at that point TpS 2, rather than a number as in ordinary situations. The analysis of such fields is strongly motivated by applications, for instance polarization ex...
We have assembled a wide spectral range, allelectronic spectro-polarimetric imager utilizing an acousto-optic tunable filter (AOTF), a liquid crystal variable retardation plate, and real-time, softwareadaptable signature masks. This combination of rapidly adjustable parameters allows operation at 30/sec. frame rate, and near real time adaptability to changing target signatures. The spectral cap...
Nonlinear Compton scattering is a promising source of bright gamma-rays. Using readily available intense laser pulses to scatter off the energetic electrons on one hand allows significantly increase total photon yield, but other leads dramatic spectral broadening fundamental emission line as well its harmonics due pulse shape induced ponderomotive effects. In this paper we propose avoid in by u...
in this paper, we investigate variation of the wavelength, intensity and polarization of the self-assembled inas/gaas quantum dots emission by microphotoluminescence spectroscopy at the liquid helium temperature. the microcavity wafer sample is grown by molecular beam epitaxy (mbe) and chemically etched into the micropillar structure (with elliptical cross section - long and short axis 2µm×1.5µ...
The structural dynamics of thin films consisting of tricarbonyl (1,10-phenanthroline)rhenium chloride (RePhen(CO)(3)Cl) linked to an alkyl silane monolayer through a triazole linker synthesized on silica-on-calcium-fluoride substrates are investigated using ultrafast infrared (IR) techniques. Ultrafast 2D IR vibrational echo experiments and polarization selective heterodyne detected transient g...
Context. We investigate non-Zeeman circular polarization and linear polarization levels of up to 1% of 12CO spectral line emission detected in a shocked molecular clump around the supernova remnant (SNR) IC 443, with the goal of understanding the magnetic field structure in this source. Aims. We examine our polarization results to confirm that the circular polarization signal in CO lines is cau...
