2017版の改善点について(英文)

  • Vectorial electromagnetic wave mode solver for microcavity model, based on a frequency domain finite difference (FDFD) method. This model has been demonstrated for VCSELs and should enhance the functionality for complex structures with oxide confinement and surface relief features.
  • Two-photon absortion model implemented for use in high-power diode lasers.
  • New compact semiconductor material model to better account for experimental IQE and IV data in Diode/LED simulation. This model replaces the fully coupled non-linear Drift-Diffusion equations with a simplified linear solution of the Poisson equation, greatly speeding up the simulation and enhancing the convergence.
  • Resonant cavity solar cell or PD with microcavity enhancements to the dipole moments and photon recycling.
  • Additional material models to tackle divergence in thermal simulation. Especially useful for high power broad-area thermal simulation.
  • Convenient external heat source definition enabled, greatly simplifying many types of thermal simulation.
  • Perturbation numerical model in lateral mode eigen value problem. Improvement in speed and stability.
  • Photon balance model for 3D simulations to rigourously enforce energy conservation. Available as alternative to the conventional round-trip gain solution method.
  • Extra flexibility and better management of divergence stall, restart and continuation in non-linear Newton method.
  • Resistive switching model suitable for RRAM application.
  • Improvements in mesh generation and BPM initialization.
  • Improvements in GUI, especially Semicrafter for complicated GDS input.
