Nonlinearity management of photonic composites and observation of spatial-modulation instability due to quintic nonlinearity
Albert S. Reyna, Cid B. de Araújo
We present a procedure for nonlinearity management of metal-dielectric composites. Varying the volume fraction occupied by silver nanoparticles suspended in acetone we could cancel…

Distinguishing orbital angular momenta and topological charge in optical vortex beams
Anderson M. Amaral, Edilson L. Falcão-Filho, Cid B. de Araújo
In this work we discuss how the classical orbital angular momentum (OAM) and topological charge (TC) of optical beams with arbitrary spatial phase profiles are related to the local…
