Optical transition probabilities and compositional dependence of Judd-Ofelt parameters of Er3+ ions in fluoroindate glass
(1995-09-01)
Fluoroindate glasses containing 1, 2, 3, and 4 mol% ErF3 were prepared in a dry box under an argon atmosphere. Absorption spectra of these glasses at room temperature were obtained. The Judd-Ofelt parameters Ωλ (λ = 2, 4, ...

Study of the glass transition temperature of as-s glasses for the fabrication of chalcogenide optical fibers
(2013-09-01)
Values of glass transition temperature (Tg) and of linear expansion coefficient (α) for Asx S100-x glasses were measured in the range of concentrations 35 × 42. Because of the importance of the glass formation region 35 × 42 ...

Inversion in the temperature coefficient of the optical path length close to the glass transition temperature in tellurite glasses
(American Institute of Physics (AIP), 2009-06-22)
In this study, thermal lens spectrometry was applied to determine the thermo-optical properties of fragile tellurite glasses as a function of temperature, close to the glass transition region. The results showed an inversion ...

Experimental observation of phase-transition-like behavior in an optical simulation of single-qubit game
(2020-08-01)
Phase-transition-like behavior in quantum games has been studied in recent years as a strategy to deal with abrupt changes in the expected payoff of quantum players. More precisely, such behavior is investigated in the ...
Front propagation transition induced by diffraction in a liquid crystal light valve
(OSA - The Optical Society, 2019)
Driven optical systems can exhibit coexistence of equilibrium states. Traveling waves or fronts between different states present complex spatiotemporal dynamics. We investigate the mechanisms that govern the front spread. ...
