Soliton formation and collapse in tunable waveguide arrays by electro-optic effect

Abstract

Light propagation in periodically poled lithium niobate (PPLN) waveguide arrays is numerically investigated. By employing the concept of a linear focusing effect, we propose a brand new method to control discrete diffraction and spatial solitons in PPLN waveguide arrays by electrical field. Simulated results are presented, and the principle is discussed to demonstrate the feasibility of the method.
