Paper Abstract

An approximate solution has been presented for the single-input nonlinear optical directional coupler under the most commonly used condition: operating near the critical power. By introducing the approximation in previous step, a simplified integral equation has been obtained. It can be integrated as simple functions instead of elliptic functions. Numerical examples of our results have been given and compared with the exact solution and the approximate solution derived by A. T. Pham et al. Our results are more accurate than that of A. T. Pham et al.
