Continuous Community Driven Improvement in PICWave 6.1.2

PICWave undergoes continuous improvements lead by community feedback in this latest version.

This includes:
        • Allowing for arbitrary signal functions (also controlled with variables).
        • Improvements to the kappa calculator for gratings.
        • Improvements to voltage dependent QCSE modelling including saturation effects.
        • Expanded support for filtering modes by their properties.
        • Multiple bug fixes.

Small Reflections, BIG Impact with EPIPPROP 3.5

Facet reflections can now be acounted for in EPIPPROP for both AWGs and Echelle gratings. The effects of this can be shown in our latest example where an AWG is exported to PICWave.
Additionally, support for mode filtering has been expanded so modes can be filtered by effective index, polarisation, confinement factor, and other further mode properties.

   EPIPPROP 3.4 also includes:
        • Significant improvements to uniform FDM solver's accuracy for specific mode properties.
        • Multiple bug fixes.

Multi Topology (MT)-FIMMPROP; Our Latest Innovation for Waveguide Simulations

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 combines the function of 3 traditional photonics design tools into one - a component simulator, a circuit simulator and a layout tool with GDS-II generation/export

  • 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.

Improvements across the board with OmniSim 8.1

We’re happy to announce OmniSim’s latest version 8.1 with upgrades in many areas. To name a few:
        • The total field/ scattered field exciters are now included in the FDTD engine, giving users the tools to conveniently investigate scattering due to an individual element in a bound volume.
        • Efficiency gains have been made in both FDTD and FETD when rerunning simulations if the device is unchanged since a previous calculation by reusing rendered structures/ meshes that have been built.
        • Beam exciters in the ZX plane can now be titled, offering further freedoms for simulations with FDTD and 2D FETD.
        • Multiple bug fixes.

Simulating Nitride Lasers with Harold 7.1

We are pleased to announce the release of Harold version 7.1. This update features a wurzite material model to allow simulation of short wavelength nitride-based devices.

   Harold 7.1 also includes:
        • Support for non-linearly graded layers.
        • A thermionic emission model for computing carrier flow across heterojunctions in HaroldXY and VCSEL.
        • Improvements to the accuracy of the refractive index spectra in HaroldQCSE.
        • Multiple bug fixes.
