Experience Lumerical's 2019a Release

Advancing the State of the Art

Lumerical has delivered a broad range of state-of-the-art features to meet challenging customer requirements for performance, usability and accuracy. Notable features include:

  • refractive index material data import from online sources to increase usability and accuracy;
  • harmonic inversion analysis of time signals to greatly reduce simulation time for many FDTD and DGTD simulations;
  • S-parameter analysis with automatic symmetry detection to eliminate unnecessary simulations and speed compact model development;
  • automatic IV curve tracing for efficient and stable simulation of next generation photodiodes such as APDs;
  • support for Intel MPI to increase simulation speed through optimal use of high core count workstations; and
  • new initial conditions for the powerful DGTD solver to enable a broader range of applications including modal extraction for plasmonic and metamaterial devices.

Quicker Results via the new Application Gallery

The new Application Gallery available within Lumerical tools includes proven design and optimization examples for applications including couplers, ring modulators, photonic resonators, CMOS image sensors, and many more. The applications provided enable photonic component designers to take advantage of validated examples, delivered in-product, providing them with a significant head start in their design work. Each example in the Application Gallery takes advantage of the latest release 2019a features and includes models, schematics and associated scripts that can be modified to design and optimize the ideal component for the designer’s application much faster than the traditional start from scratch approach. Designers uniquely benefit from the in-product discovery and download of these examples that target typical, key use cases, and are seamlessly delivered to the product via a web-based delivery mechanism.

Ecosystem Design Flows Support Photonic Integrated Circuit (PIC) Designers

The new INTERCONNECT-Tanner interoperability option available with the 2019a release enables a design flow familiar to Tanner users. Circuit designers can now work with validated Mentor foundry process design kits (PDKs) paired with associated INTERCONNECT compact model libraries (CMLs) to achieve a closed loop design cycle. This flow includes circuit layout in Tanner L-Edit Photonics complemented by Mentor’s new LightSuiteTM Photonic Compiler, physical verification with Calibre eqDRC, and circuit simulation with INTERCONNECT. Used in conjunction with the recently released TowerJazz PH18 PDK or Mentor’s GPIC iPDK, this flow provides an invaluable resource for PIC designers to tape-out faster with predictable results and for PDK developers.

Lumerical’s 2019a release enhances support within the Cadence® Virtuoso® ADE Explorer for streamlined electro-optical simulation. The new release enhances the transient co-simulation capabilities for electro-optical integrated circuits and provides a new frequency response analysis solution for such designs. In addition, a new PDK verification feature assures PDK quality by checking consistency of the PDK components across files used in the Lumerical/Cadence EPDA flow. It also enables Lumerical customers to take advantage of Cadence’s recently announced Virtuoso CurvyCore™ infrastructure, immediately upon its release. The 2019a release further enhances the industry-leading EPDA design flow that offers dedicated photonic simulation with INTERCONNECT and electronic-photonic co-simulation when used in conjunction with Cadence Spectre AMS Designer.
