A New Domain of Waveguide Devices with Multi Topology (MT)-FIMMPROP

We’re pleased to announce the release of MT- FIMMPROP, the new additional module to FIMMPROP that expands the use of our market leading EigenMode Expansion method into a new domain of waveguide devices.

  • Simulation and Layout Environment – MT-FIMMPROP’s fully schematic environment allows users to see devices as they would appear on chip; this means MT-FIMMPROP now functions as a layout tool with GDS-II export in a single click.

  • Field Visualisation – The results of MT-FIMMPROP’s simulations are now displayed on the geometry of the device giving a more visual opportunity to examine the behaviour of devices for iterative design workflows.

  • Computational Regions – MT-FIMMPROP allows users to define computational regions that can span coupling regions or conform to the shape of arbitrarily defined paths. This allows multiple simulations to be combined natively.

Simulating the Smallest of Details with EPIPPROP 3.4

We are pleased to announce the release of EPIPPROP version 3.4. This update allows you to examine the tolerance of your device with real world effects:
        • Model manufacturing defects by introducing variations to the layer thickness with either a random noise profile or an imported file.
        • Vary the temperature and refractive index over the area of the chip as defined by an import file.

In addition, the new ‘Etch & Fill’ process type allows for far more flexible waveguide geometries.

   EPIPPROP 3.4 also includes:
        • Improved calculation of optical path length for each output waveguide.
        • Multiple bug fixes.

Improved Accuracy in Quantum Wells with Harold 7.0

Harold’s newest update comes with the new k.p model, taking into account a non-parabolic band structure in quantum wells (QWs). This allows you to model gain, spontaneous emission, and perform carrier density calculations.

   Harold 7.0 also includes:
        • Support for forward-bias voltages in Harold QCSE.
        • Editable boundary conditions in the HaroldXY mode solver.
        • Improvements to the procedure for solving the Schrödinger equation in QWs.
        • Multiple bug fixes.

Even More Flexibility in FIMMWAVE 7.4

We’re pleased to announce the release of FIMMWAVE version 7.4. We’ve been increasing the amount of things that are possible when modelling Euler bends. Now you can model partial Euler bends which combine the Euler-bend sections with a constant-curvature bend. Such composite bends can be used to reduce bend losses in the devices you design.
