Multicore fiber-Bragg-grating-based directional curvature sensor interrogated by a broadband source with a sinusoidal spectrum.

Optics letters

Zheng D, Madrigal J, Chen H, Barrera D, Sales S.
PMID: 28914939
Opt Lett. 2017 Sep 15;42(18):3710-3713. doi: 10.1364/OL.42.003710.

A simple, spectral-drift-insensitive interrogation scheme for a multicore fiber Bragg grating (FBG)-based directional curvature sensor is proposed. The basic principle is to transform the wavelength shift of FBGs into the reflected power variation, which is accomplished by utilizing a...

Physical review letters

Marcuzzi M, Minář J, Barredo D, de Léséleuc S, Labuhn H, Lahaye T, Browaeys A, Levi E, Lesanovsky I.
PMID: 28234523
Phys Rev Lett. 2017 Feb 10;118(6):063606. doi: 10.1103/PhysRevLett.118.063606. Epub 2017 Feb 10.

We explore the dynamics of Rydberg excitations in an optical tweezer array under antiblockade (or facilitation) conditions. Because of the finite temperature the atomic positions are randomly spread, an effect that leads to quenched correlated disorder in the interatomic...

Microbial communities inhabiting the deep-sea salt-saturated anoxic lakes of the Eastern Mediterranean operate under harsh physical-chemical conditions that are incompatible with the lifestyle of common marine microorganisms. Here, we investigated a stable three-component microbial consortium obtained from the brine...
