Lumerical worked with professor Lukas Chrostowski from University of British Columbia and developed the INTERCONNECT integration with KLayout. The KLayout integration is layout driven only. This integration provides user the ability to test and verify the layout design before fabrication. An EBeam compact model library that contains several frequently used components, i.e., grating couplers, terminators, ring modulators, is provided that users can directly use for their layout design and circuit verification.
The following diagram shows the work-flow of the integration.
