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…

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…

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…

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…
