TL properties of RE-Doped and Co-doped Sol-gel Silica Rods. Application to Passive (OSL) and Real-time (RL) Dosimetry

Mourad Benabdesselam, J. Bahout, Franck Mady +8

Two rods made from sol-gel silica have been doped with Ce ions or co-doped with Ce and Tb ions respectively. First, a thermoluminescence (TL) characterization of the trapping and l…

Nonlinearity-induced Scattering Zero Degeneracies for Spectral Management of Coherent Perfect Absorption in Complex Systems

Cheng-Zhen Wang, John Guillamon, William Tuxbury +2

We develop a Coherent Perfect Absorption (CPA) protocol for cases where scale invariance is violated due to the presence of nonlinear mechanisms. We demonstrate, using a microwave…

Design and fabrication of dispersion controlled highly nonlinear fibers for far-tuned four-wave mixing frequency conversion

Sidi-Ely Ahmedou, Romain Dauliat, Alexandre Parriaux +8

We report on the conception, fabrication and characterization of a new concept of optical fiber enabling a precise control of the ratio between the 2nd and 4th-order of chromatic d…

Breaking of reciprocity and the Pancharatnam-Berry phase for light scattered by a disordered cold atom cloud

P. H. N. Magnani, P. G. S. Dias, M. Frometa +7

Collective effects on the light scattered by disordered media such as Anderson localization and coherent backscattering critically depend on the reciprocity between interfering opt…
