Spontaneous 2D modulation instability in second harmonic generation process

Spontaneous 2D modulation instability in second harmonic generation process

Two-dimensional modulation instability (2DMI) is experimentally demonstrated in a classical second harmonic generation setup. The spatial spectrum is measured and reveals typical 2DMI bands, in agreement with the analytical MI model. These observations are confirmed by (2+1)D numerical simulations....

Zusammenfassung:Two-dimensional modulation instability (2DMI) is experimentally demonstrated in a classical second harmonic generation setup. The spatial spectrum is measured and reveals typical 2DMI bands, in agreement with the analytical MI model. These observations are confirmed by (2+1)D numerical simulations. ►2D modulation instability is investigated in second harmonic configuration. ►Experimental demonstration is provided. ►Spatial spectrum is measured and reveals typical 2DMI bands. ►Observations are confirmed by (2+1)D numerical simulations and an analytical model.
