Metric - Mode expansion tool for rectangular integrated optical circuits Metric: Tools for semianalytic modeling in integrated optics / photonics, simulations of lossless 2D 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), and the computation of Floquet-Bloch-modes for rectangular periodic structures in 2D. A series of application examples, embedded in the html manual, complements the downloadable, commented C++ sources.
WMM mode solver WMM: A quasianalytic mode solver for rectangular dielectric integrated optical waveguide channels (3D configurations with 2D cross sections). Besides the actual procedures for guided mode analysis, the programs provide facilities for the evaluation of perturbational expressions, and an implementation of coupled mode theory. The html manual includes the downloadable, commented C++ sources, accompanied by several application examples.
OMS - 1D multilayer slab waveguide mode solver - Online ! OMS: A mode solver for optical dielectric multilayer slab waveguides with 1D cross sections. Following the waveguide definition in terms of refractive indices, layer thicknesses, and the vacuum wavelength, the script calculates the propagation constants / effective indices of guided modes and allows to inspect the corresponding optical field patterns. Facilities for evaluating simple parameter scans (modal dispersion properties) are provided. The solver is intended as a basic tool for integrated optics design, in particular for purposes of demonstration.
EIMS - 2D effective index mode solver - Online ! EIMS: Similar to its 1D counterpart, this script calculates and visualizes the guided fields of dielectric integrated optical waveguides with two-dimensional light confinement and weak lateral guiding. Note the remarks on the variant of the effective-index approximation the mode solver relies on.
MuLS - Plane wave reflection at dielectric multilayers - Online solver ! MuLS: A solver for problems of plane wave reflection from dielectric multilayer systems at oblique incidence. Given the stack definition in terms of refractive indices, layer thicknesses, vacuum wavelength, and the angle of incidence, the script calculates reflectance and transmittance properties for s- and p-polarized waves, and allows to inspect the optical field profiles. Facilities for evaluating parameter scans / spectra are available. The script can serve as a basic tool for the design of dielectric multilayer coatings / reflectors / filters, in particular for purposes of demonstration.
QuEPS - 2-D frequency domain solver for rectangular optical guided-wave scattering problems - Online ! QuEPS: A frequency domain solver for 2-D rectangular optical guided-wave scattering problems. The scalar polarized 2-D Helmholtz equations are addressed, on a rectangular computational domain with transparent boundary conditions that permit guided wave in- and outflux. Following the problem specification in terms of interface positions, a matrix of refractive index values, polarization and wavelength parameters, and guided wave input, the script determines modal output amplitudes (elements of the scattering matrices), and the power levels associated with guided and nonguided directional outgoing waves (transmittances / reflectances, power balance). Facilities for detailed inspection of the optical electromagnetic field are provided, including animations of the harmonic oscillations in time, with options for exporting figures and data.
Wavelength / frequency / energy equivalents WaFE: Conversion between quantities that characterize the propagation of harmonic electromagnetic waves in vacuum. This concerns wavelength, wavenumber, spectroscopic wavenumber, frequency, angular frequency, time period, and photon energy, (mostly) in SI units.
Term evaluation Teval: A script that can evaluate simple C-style expressions. The program knows about the numerical values of some common physical constants, hence it is in particular useful for a certain class of basic exercises in physics courses ...
