【Abstract】 Dependence of coupling coefficient on guided wave power of a nonlinear directional waveguide coupler formed by two optical planar waveguides placed in close proximity is discussed. Formulas and procedure of calculation is presented for the interaction region being covered with nonlinear Kerr type dielectric material. Numerical examples and discussions are given for both self_focussing and self_defocussing material.更多还原
