Nonlinear coupled equations that describe propagation of optical pulses in waveguide structures under the slowly varying envelope approximation are solved by a simple explicit finite‐difference scheme.The technique, which is based on upwind differencing, is used for modeling of Kerr‐nonlinear structures with microring resonators in all‐pass filter configuration. We show numerical examples that demonstrate existence of self‐pulsing and chaotic solutions. © 2011 Wiley Periodicals, Inc.
