title: Path-integral formulation of nonuniform optical coupled wave problems.
abstract: Path integration is presented as a method of solving 1-D optical coupled wave problems, in which the parameters of the system vary with distance. The method is derived by thin section decomposition and as a perturbation solution to the general matrix problem. Results are obtained as an infinite series solution, which is evaluated for a number of examples; in all cases, the solution is in agreement with that found by more conventional methods.
