Spatial beam self-cleaning in tapered Yb-doped GRIN multimode fiber with decelerating nonlinearity
A. Niang, D. Modotto, A. Tonello +12
We experimentally demonstrate spatial beam self-cleaning in an Yb-doped graded-index multimode fiber taper, both in passive and active configurations. The input laser beam at 1064…
99.992 % Si CVD-grown epilayer on 300 mm substrates for large scale integration of silicon spin qubits
V. Mazzocchi, P. G. Sennikov, A. D. Bulanov +7
Silicon-based quantum bits with electron spins in quantum dots or nuclear spins on dopants are serious contenders in the race for quantum computation. Added to process integration…
On the possibility of mid-IR supercontinuum generation in As-Se-Te/As-S core/clad fibers with all-fiber femtosecond pump source
E. A. Anashkina, V. S. Shiryaev, G. E. Snopatin +2
We propose and optimize theoretically a supercontinuum (SC) laser source in the mid-IR based on using As-Se-Te/As-S core/clad step-index fibers and a femtosecond all-fiber laser sy…
Development of As-Se tapered suspended-core fibers for ultra-broadband mid-IR
E. A. Anashkina, V. S. Shiryaev, M. Y. Koptev +2
We designed and developed tapered suspended-core fibers of high-purity As39Se61 glass for supercontinuum generation in the mid-IR with a standard fiber laser pump source at 2 m.…
Core-clad Pr(3+)-doped Ga(In)-Ge-As-Se-(I) glass fibers: preparation, investigation, simulation of laser characteristics
E. V. Karaksina, V. S. Shiryaev, M. F. Churbanov +3
Core-clad fibers on the basis of high-purity 1300 ppmw Pr(3+)-doped Ga-Ge-As-Se and 2000 ppmw Pr(3+) -doped In-Ge-As-Se-I glasses have been prepared. The minimum optical losses of…
Determination of Low Loss in Isotopically Pure Single Crystal Si at Low Temperatures and Single Microwave Photon Energy
Nikita Kostylev, Maxim Goryachev, Andrey D. Bulanov +2
The low dielectric losses of an isotropically pure single crystal Si sample were determined at a temperature of 20 mK and at powers equivalent to that of a single photon. Wh…
Infrared luminescence in Bi-doped Ge-S and As-Ge-S chalcogenide glasses and fibers
V. G. Plotnichenko, D. V. Philippovskiy, V. O. Sokolov +4
Experimental and theoretical studies of spectral properties of chalcogenide Ge-S and As-Ge-S glasses and fibers are performed. A broad infrared (IR) luminescence band which covers…
Thermal behavior of NIR active centers in Bi-doped optical fibers
D. A. Dvoretsky, I. A. Bufetov, V. V. Vel'miskin +6
The temperature dependences of optical loss and luminescence spectra have been measured in visible and NIR spectral range for Bi-doped silica and Bi-doped germanosilicate fibers fo…
IR Bismuth active centers in optical fibers: Combined excitation-emission spectroscopy
S. V. Firstov, V. F. Khopin, I. A. Bufetov +3
3D excitation-emission luminescence spectra of Bi-doped optical fibers of various compositions were measured in a wide wavelength range 450-1700 nm. Such luminescence spectra were…
Refractive index spectral dependence, Raman and transmission spectra of high-purity Si, Si, Si, and Si single crystals

V. G. Plotnichenko, V. O. Sokolov, G. E. Snopatin +1
Absorption spectra of Ni ions in 22WO--78TeO tungstate-tellurite glass were studied and Ni extinction coefficient spectral dependence was derived in the 450 -…
Thermal Conductivity of Isotopically Enriched 28Si Revisited
R. K. Kremer, K. Graf, M. Cardona G. G. Devyatykh +3
The thermal conductivity of isotopically enriched 28Si (enrichment better than 99.9%) was redetermined independently in three laboratories by high precision experiments on a total…
