Metric

Tools for semianalytic modeling in integrated optics /
photonics, simulations of configurations with rectangular
refractive index distributions. Includes a mode solver
engine for dielectric multilayer slab waveguides, and solvers for scalar and vectorial guided-wave
Helmholtz (-scattering) problems based on spectral discretizations along one
(BEP: bidirectional eigenmode propagation)
or two coordinate axes
(QUEP: quadridirectional eigenmode propagation).
Extensions concern the angled propagation of plane waves across dielectric multilayer stacks, conventional and hybrid analytical/numerical variants of coupled mode theory, a 2-to-1D
effective index treatment of 2D scattering problems, a variational effective-index-like mode solver for 3D channels (with 2D cross sections), the computation of Floquet-Bloch-modes
for rectangular periodic structures in 2D, and solvers for the bend modes of curved slab structures, the whispering gallery modes supported by 2-D circular multilayer dielectric cavities, the guided modes of circular multi-step-index optical fibers, and the bound and leaky modes of multilayer structures with complex permittivity, including surface-plasmon-polaritons (SPPs).
A series of application examples, embedded in the html manual, complements the downloadable, commented C++ sources.
