About
mode solving:
A basic requirement for the design and analysis of (planar) waveguide
circuits is the calculation of optical eigenmodes in waveguides. Eigenmodes
can be used to determine such basic properties as coupling lengths, fiber
to chip losses and mode confinement. OlympIOs enables the user to select
a dedicated solver as part of the basic or advanced mode solver module.
The benefits:
 One
of several distinct advantages offered by OlympIOs mode solver modules
is the full parameterization of waveguide geometry and calculation window
settings. Quick and easy analysis of waveguide properties is enabled as
a function of parameters. Another asset is the extensive choice of mode
solvers. Let's be honest, as far as numerical solvers go each has its
specific strengths and weaknesses. By offering the most complete range
of mode solvers, OlympIOs is unique in its capability to handle the most
demanding mode-solving challenges.
