Key Features

Perform photonic integrated circuit simulations with analyses in the time and frequency domain.

  • PIC Simulation and Design
  • EDA and PDA Interoperability
  • Statistical Analysis
  • PIC Element Libraries
  • CML Development and Distribution

With its hierarchical schematic editor, use INTERCONNECT to design and simulate photonic integrated circuits. INTERCONNECT includes frequency domain analysis, transient sample mode simulation, and transient block mode simulation. It includes sophisticated visualization and data analysis tools with support for parameter sweeps and design optimization.

Simulate and optimize your designs with familiar EDA design tools and workflows to accelerate design time and improve reliability. 

Perform corner analysis to model the effects of process variation on circuit performance. Execute Monte Carlo analysis to assess circuit performance and yield by accounting for process variations

INTERCONNECT contains an extensive standard library of passive and active optoelectronic building blocks, along with supplementary elements that enable simulations and analyze results. It includes two library extensions:

  • An element library extension for laser modelling
  • An element library extension for advanced system modelling including sophisticated fiber, amplifier, FEC encoding and equalization models

INTERCONNECT, along with Ansys Lumerical's device level tools, provides an infrastructure that supports the development and distribution of compact model libraries (CMLs) for PIC simulation and design. Typically, a CML is built upon a combination of experimentally measured data and accurate component-level simulation results using Lumerical’s device-level photonics tools.
