NEW FEATURE OptiMODE
Introducing a new application available to create a complete project out of mode solving. In most cases, the first stage of optical design is the design of the optical waveguide itself. At this stage, mode solvers are the natural simulators to use. In OptiBPM 10, one can specify materials and profiles, and then create a project using OptiMODE XS Designer.
Additional feature in OptiMODE: The solving of modes from user‐defined refractive index distributions. Import a file with any kind of refractive index distribution into the OptiMODE XS Designer.
NEW FEATURE New ADI Methods for Full Vector AnisoBPM
Introducing a new BPM simulator in OptiBPM 10 based on the Alternating Direction Implicit (ADI) technique, which is much faster than methods (Crank‐Nicholson) used in previous editions of OptiBPM. Users now have the option to select one of the two ADI techniques based on their simulation requirements.
NEW FEATURE 2D Cauchy Integral mode solver
The 2D mode solver in OptiBPM is now enhanced to find lossy and leaky modes, as well as surface plasmon modes.
This mode solver exploits the Cauchy Integral rule – where the number of poles inside a closed path in the complex plane is given from the path integral over the contour.
The algorithm sets up the dispersion equation for the given multilayer and searches for the modes in the form of poles in the complex plane. Users also have the flexibility to
change the path to look for modes elsewhere.
NEW FEATURE 3D Layout Designer
The Layout Designer is now enhanced with full three-dimensional (3D) view of the design. One can rotate, move, and view designed structures in a versatile 3D environment with zoom in/out capabilities from any angle or position. Users no longer are limited to analysis of two-dimensional refractive index cross-section to deduct the spatial shape of the design.
NEW FEATURE Modal group delay and dispersion
OptiMODE includes a special feature to plot modal index vs. wavelength. This data is displayed in the OptiMODE Results Analyzer. Users can also calculate and plot group delay and dispersion spectra.
NEW FEATURE Sellmeier definition of dispersion
With this convenient feature, OptiBPM and OptiMODE will adjust the refractive index according to the current wavelength. This is especially useful in the calculation of modal dispersion. The result will include material dispersion as well as waveguide dispersion.
