Enables HPC, Photonic Inverse Design, Design for Manufacturing, and Improved Laser Modeling

The addition of inverse design methods to Lumerical’s products has been a game changer for our photonics design efforts – they have enabled better performance and much faster optimization of grating couplers and other complex photonic components.

Lumerical Inc., a leading developer of photonic design and simulation tools, announces the 2020a release of:

  • DEVICE Suite for photonic multiphysics simulation consisting of FDTD, MODE, CHARGE, HEAT, DGTD, FEEM, MQW, and STACK;
  • SYSTEM Suite for photonic integrated circuit simulation consisting of INTERCONNECT, CML Compiler, Laser Library, and System Library; and
  • Interoperability Products including Automation API, partner integration licenses and foundry compact model libraries (CMLs).

Lumerical continues to push the innovation envelope to deliver accurate, high performance simulators in easy to use design environments for photonic designers. Lumerical’s 2020a release delivers powerful capabilities that speed time to results and improve simulation accuracy. Notable features include: support for high performance computing and cloud computing including FDTD job checkpointing and self service burst license activation; support for statistical Monte Carlo and corner case analysis for INTERCONNECT using compact models generated by CML Compiler; a new multiple quantum well gain solver; improved analysis tools for INTERCONNECT’s traveling wave laser model; improvements to photonic inverse design; a PAM4 transceiver example of multidomain optical and electrical simulation using a SPICE simulator in conjunction with Lumerical’s Photonic Verilog-A Platform, and; a range of productivity improvements including the ability to export s-parameter results to INTERCONNECT from the MODE EME sweep tool, script command import/export for optical materials, and self serve trials.

HPC and Cloud Computing
2020a enables customers to maximize simulation throughput using high performance computing (HPC) and cloud computing by optimizing use of both onsite clusters and cloud platforms. Lumerical now offers FDTD Burst Packs, a convenient method to license additional FDTD Accelerators for 10 day or 30 day increments for cloud or on-premise HPC platforms. FDTD Burst Packs enable users to quickly and seamlessly transition FDTD simulations to the cloud to take advantage of massive computing resources on demand from popular cloud computing providers.

The 2020a release delivers support for job checkpointing within Lumerical’s FDTD and FDTD Accelerator products, enabling interrupted long duration FDTD simulations to continue from where they left off. Checkpointing reduces computing costs by enabling customers to recover from hardware failures and access inexpensive spot pricing from cloud providers.

Photonic Inverse Design
The 2020a release further advances Lumerical’s photonic inverse design (PID) deployment, Lumopt, with support for global optimization. The introduction of powerful Basin hopping global optimization pushes PID optimization performance by automatically executing many local optimizations to maximize the exploration of the parameter space. Manufacturing constraints help designers adopt design for manufacturing (DFM) while producing high performing designs.

“The addition of inverse design methods to Lumerical’s products has been a game changer for our photonics design efforts – they have enabled better performance and much faster optimization of grating couplers and other complex photonic components, than with traditional sweeps and particle swarm optimizations. As always, Lumerical’s support team has done an excellent job helping us make the most of the new design capabilities,” said Michael Moebius, Senior Member of the Technical Staff at Draper.

Statistical Monte Carlo/Corner Case Analysis
CML Compiler now generates statistical compact models, enabling DFM techniques. These models enable Monte Carlo analysis and corner analysis with the 2020a release of INTERCONNECT.

“Lumerical is heavily committed to pushing the envelope for simulation accuracy with our foundry partners in their effort to offer high quality manufacturing robust PDKs. This release offers a unique solution for modeling process variations to help our customers keep pace with the rapid growth of the photonics landscape,” said James Pond, CTO at Lumerical.

Improved Laser Modeling
The 2020a release features a new multiple quantum well (MQW) solver with related analysis tools for INTERCONNECT’s traveling wave laser model (TWLM). Lumerical now offers a comprehensive design flow for modeling edge emitting lasers that includes device level physical simulation combined with circuit level simulation. Automation API enables designers to integrate MQW and TWLM with Lumerical's DEVICE Suite to include charge and heat transport effects. Laser simulation and analysis results include material and threshold gain, laser spectrum and SMSR, steady state LI, and transient response. The combined flow offers an ideal modeling tool for applications such as SOAs, edge emitters, and electroabsorption modulators.

Lumerical’s 2020a release is available for download immediately.
