Abstract
A numerical study is conducted of a three-waveguide nonlinear directional coupler. Markedly sharper transmittance characteristics than the well-known two-waveguide coupler are obtained at the expense of a higher switching power. Over longer distances transitions from quasi-periodic to chaotic behavior and back take place as the power is varied.Keywords
