Key Features

Design and optimize a wide range of photonic integrated circuits using INTERCONNECT’s extensive library of models, ready to use foundry calibrated models, or customized compact models. 

  • PIC Simulation, Design, and Optimization
  • Multiplatform EDA Enablement
  • PDK Driven Design

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.

Easy workflows in qINTERCONNECT enable non-quantum theorists to evaluate the fidelity and probability of success in the presence of fabrication imperfections, loss, and partially distinguishable photons.

Design everything from SOAs and DFB lasers to complex external cavity DBR or sampled grating Vernier lasers in hybrid or integrated photonic designs.
