We demonstrate a non-classical photon emitter at near infrared wavelength based on a single (In, Ga)As/GaAs epitaxially grown columnar quantum dot. Charged exciton complexes have been identified in magneto-photoluminescence. Photon auto-correlation histogr ...
A review. Nitroxyl (HNO) is a biol. signaling agent that displays distinctive reactivity compared to nitric oxide (NO). As a consequence, these two reactive nitrogen species trigger different physiol. responses. Selective detection of HNO over NO has been ...
We report the discovery of a gravitationally lensed hyperluminous infrared galaxy (intrinsic L-IR approximate to 10(13) L-circle dot) with strong radio emission (intrinsic L-1.4 GHz approximate to 10(25) WHz(-1)) at z = 2.553. The source was identified in ...
Purpose Repeated-sprint training in hypoxia (RSH) was recently shown to improve repeated-sprint ability (RSA) in cycling. This phenomenon is likely to reflect fiber type-dependent, compensatory vasodilation, and therefore, our hypothesis was that RSH is ev ...
Over the past decade, a growing interest appeared for III-nitride semiconductors, in view of their potential applications in intersubband (ISB) devices. If these materials are nowadays famous, particularly for having revolutionized domestic lighting thanks ...
Photonic crystal (PhC) cavities combine ultra-high quality (Q) factors with small mode volumes, resulting in an enhancement of the light-matter interaction at the nanoscale, which, beyond fundamental studies is advantageous for countless applications in ph ...
Organic photodetectors are interesting for low cost, large area optical sensing applications. Combining organic semiconductors with discrete absorption bands outside the visible wavelength range with transparent and conductive electrodes allows for the fab ...
Mid-infrared absorption spectroscopy is a powerful tool for optically probing the molecular structure of biological samples. However, using conventional approaches, IR measurements on small quantities of molecules are extremely challenging due to sensitivi ...
We demonstrate 1.5W sub-picosecond pulsed source near 2μm. Cavity-less source is based on integrated association of 3rd order Raman wavelength-shifting and thulium amplification. Coherent spectrum of 61.5nm with 49% pump power conversion efficiency is achi ...
Infrared pulses with large spectral width extending from 1.2 to 3.4 μm are generated in the organic crystal DAST (4-N, N-dimethylamino-4′-N′-methylstilbazolium tosylate). The input pulse has a central wavelength of 1.5 μm and 65 fs duration. With 2.8 mJ in ...
