Published in 2021 at "International Journal of Non-Linear Mechanics"

DOI: 10.1016/j.ijnonlinmec.2021.103788

Abstract: Abstract The nonlinear modulation of waves in a metamaterial mass-in-mass lattice model is studied. The governing continuum nonlinear equation is obtained from the original discrete model. The important differences in the modulated nonlinear wave dynamics… read more here.

DOI: 10.1039/d2dt01320g

Abstract: Tellurate crystals are attractive for developing new nonlinear optical (NLO) materials in the mid-infrared region due to their wide transmission window. In this work, we report a quaternary tellurate oxide crystal, Li2GeTeO6, which exhibits a… read more here.

Published in 2018 at "Journal of Lightwave Technology"

DOI: 10.1109/jlt.2018.2794475

Abstract: Nonlinear frequency division multiplexed (NFDM) systems are considered when data are modulated in both parts of the nonlinear Fourier spectrum: Continuous spectrum and discrete spectrum. An efficient algorithm is introduced to generate a time-domain signal… read more here.

Published in 2021 at "Applied optics"

DOI: 10.1364/ao.420663

Abstract: A phase spread frequency sampling method is proposed. This method can be used to correct the nonlinearity in the beat frequency of a measurement signal. The proposed method expands the phase of the auxiliary interference… read more here.
