Observation Of Discrete Modulational Instability

Abstract

The observation of discrete modulational instability (MI) in an optical system is discussed. In bulk material with positive nonlinearity, a high intensity beam will either form a bright spatial soliton or will break up due to MI. The spatial stability properties of the waves in discrete optical system are also discussed. Arrays of 101 AlGaAs waveguides are used for propagating wide, high power beams from a picosecond optical parametric amplifiers, and also observed the output intensity distribution for different powers and propagation angles. An increase to 72 W of power gives rise to the growth of noise from the sources because of discrete MI in the normal diffraction region, while no such growth is observed in the anomalous diffraction region.
