Lumerical Compact Model Library

Design Automation tools, informed by Process Design Kits (PDKs), are the foundation of scalable integrated circuit design, enabling reliable and cost-effective fabrication of highly complex circuits and systems. The Lumerical Compact Model Library (LCML) has been developed to assist integrated photonics designers and researchers develop innovative components and accurate compact models for photonics PDKs.

Accessing the LCML

The LCML is available to all licensed Lumerical users. The complete LCML is comprised of two packages:

  • Lumerical Compact Model Library (LCML)
  • LCML Developer Resources

The complete LCML uses Lumerical's suite of photonic component and circuit design tools.

FDTD Solutions MODE Solutions DEVICE Charge Transport DEVICE Heat Transport INTERCONNECT

The packages are available under INTERCONNECT section in the Lumerical Download Center.

 

LCML Components

LCML WGS LCML Y The LCML package is a library of passive and active photonic elements for INTERCONNECT, Lumerical’s photonic integrated circuit simulator. The elements can be used for design and modeling of photonic integrated circuits or, in combination with the LCML Developer Resources, as a reference for developing a calibrated model library for a photonic PDK.

Compact Model Library and PDK Development

The LCML Developer Resources provide component level simulation files and reference workflows to develop compact models calibrated to your specific performance requirements or fabrication process. Utilizing a combination of measured data and component level simulations, the workflows can be used to define the reference LCML element parameters and create a calibrated model library for photonic PDKs.

Using the Developer Resources, models are defined using various techniques, including:

  • Lookup tables populated from extracted S-parameters based on 2D/3D component simulations
  • Curve fitting of experimental data into analytical equations describing component behavior

Complex active devices such as a Mach-Zehnder modulator or a photodetector can be defined through workflows using Lumerical's component level solvers, FDTD Solutions, MODE Solutions, and DEVICE.

Collaborative Development Community

Knowledge Exchange

The LCML is supported through Lumerical’s Knowledge Exchange. Design and simulation methodologies for active and passive components and compact models are discussed, enabling a continuous evolution and improvement of the scope, accuracy and quality of the LCML elements and workflows. Along with learning how to get the most from the LCML for your application, join the conversation to suggest improvements in the methodology, request additional components for the library or suggest design ideas for future implementation.
