A recently introduced optimal control theory method for optical waveguide design is applied to Y-branch waveguides and Mach–Zehnder modulators. The method simultaneously optimizes many parameters in a chosen design scheme; computational effort scales mildly with the number of parameters considered. Significant improvement in guiding efficiency relative to intuitively reasonable initial parameter choices is obtained in all cases.

  16. Note that V(x, z) ≅ -kΔn(x, z), where Δn(x, z) ≡ neff(x, z) - n0 is the deviation of the index from the reference value n0, which in the waveguides of interest here is much less than the reference value itself, i.e., Δn/n0 ≪ 1.

  19. Criteria other than output quality can in principle be included in the cost function. Some possibilities were considered in Ref. 5. Here for simplicity we assume that output quality is the only important issue.
  20. Other criteria for optimal guiding are possible, for example, maximization of the integrated beam intensity within the boundaries of the guide at its output. There exists an appropriate projection operator analogous to the one given in Eq. (5) for each optimal guiding criterion.

  22. To check that the paraxial equation yields an accurate approximation to the full Helmholtz equation, we utilized the numerical method presented in Ref. 23 to solve the latter equation for several parameter sets considered in this paper. The results were found to be essentially identical to those obtained from the paraxial equation, giving us confidence that the paraxial equation suffices for the systems of interest here. Development of an OCT procedure for direct optimization of wave propagation according to the Helmholtz equation presents an interesting problem for further research.
