| Abstract: | Dependence of coupling coefficienct 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 the 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. |
