We experimentally demonstrate that the stability of cw and mode-locked erbium-doped fiber ring lasers can be improved significantly with a semiconductor optical amplifier (SOA) inside the cavity.
Gain dynamics in two quantum-dash semiconductor optical amplifiers of different lengths emitting in the 1.55 µm region are investigated experimentally and compared.
Single crystals of Bi2M4Co2Oy phases with M=Ca, Sr, and Ba were synthesized by the flux method. These compounds are analogous to Bi-2212 superconducting systems with cobalt replacing copper.
The photoactivity of n-TiO(2) (rutile) pigment is reduced by thermal quenching, by ball-milling and by adsorption of iron ions.
We analytically study the cross-phase-modulation (XPM) impact on 40-Gb/s DQPSK from 10Gb/s OOK channels, revealing it dependence on dispersion map and channel plan, and showing the suppression of t

KGaA, Weinheim The adsorption behavior of collagen on solid surfaces is a process that determines the role of this protein to mediate cell?material interaction.
This paper formalizes and tests two key assumptions of the concept of suprasegmental timing: segmental independence and suprasegmental mediation.
We have measured the surface acoustic wave velocity shift in a GaAs/AlGaAs heterostructure containing a two-dimensional electron system (2DES) in a low-density regime ( 10(10) cm(-2)) at zero magne
The principal and up to six higher order localized acoustic surface modes from CaF sub 2 films grown epitaxially on Si (111) have been observed using Brillouin scattering.
