PMID: 26906847
Opt Express. 2016 Feb 08;24(3):2774-87. doi: 10.1364/OE.24.002774.

Adopting an exact solution to four-wave mixing (FWM), wherein harmonic evolution is described by the sum of two Bessel functions, we identify two causes of amplitude to phase noise conversion which impair FWM saturation based amplitude regenerators: self-phase modulation...

Opt Express. 2017 Feb 20;25(4):3252-3258. doi: 10.1364/OE.25.003252.

We report a nonlinear signal processing system based on a SiGe waveguide suitable for high spectral efficiency data signals. Four-wave-mixing (FWM)-based wavelength conversion of 10-Gbaud 16-Quadrature amplitude modulated (QAM) and 64-QAM signals is demonstrated with less than -10-dB conversion...

Modelling accretion disc and stellar wind interactions: the case of Sgr A.

Monthly notices of the Royal Astronomical Society

Employing both multireference configuration interaction (MRCI) and density functional theory (DFT) methods, we have studied the interaction of O₂ with a tetrahedral Al₄ cluster in the total spin triplet state. For a parallel to the base approach of O₂...

Elimination of the chirp of optical pulses through cascaded nonlinearities in periodically poled lithium niobate waveguides.
