Discrete self-focusing in nonlinear arrays of coupled waveguides

Abstract

We show that a nonlinear array of coupled waveguides can exhibit discrete self-focusing that in the continuum approximation obeys the so-called nonlinear Schrödinger equation. This process has much in common with the biophysical model of Davydov.
