Spatio-temporal doubly periodic waves in phase-mismatched second-harmonic generation
In this Letter we present the analytical and numerical investigation to characterize the formation of quadratic doubly periodic waves, originating from coherent modulation instability in a dispersive quadratic media in the regime of cascading second-harmonic generation. Such an endeavor has not been undertaken before despite the growing relevance of double-periodic solutions as the precursor of highly localized wave structures. Unlike the case with cubic nonlinearity, the periodicity of these quadratic nonlinear waves can be also controlled by the wave-vector mismatch in addition to the initial input condition. Our results may impact widely on the formation, excitation and control of extreme rogue waves and the description of modulation instability in quadratic optical medium.
