This InP photonics Design Kit contains the building blocks for the Multi Project Wafer runs offered by Fraunhofer HHI (Heinrich Hertz Institute)

The Process Design Kit (PDK) for InP photonics is a licensed plug-in library library for OptoDesigner and OptSim Circuit and supports the Multi Project Wafer runs provided by Fraunhofer HHI through the technology broker JePPIX or in direct commercial collaboration with HHI.

HHI offers two PDKs: V5.4.1 standard open PDK and HHI EOPM 6.0.0 PDK, an advanced PDK that contains EOPM blocks.

The HHI design kit (5.4.1) content is supported by the bi-directional interface between Synopsys’ circuit and layout photonic solutions, OptSim Circuit and OptoDesigner.

In addition to the photonic elements from the standard generic design library, the PDK contains technology-specific information such as mask layer names, design rules, validated building blocks, s-matrix compact models, die templates for layout generation, and GDS file settings.

The HHI PDK EOPM 6.0.0 is supported at the layout level and contains the standard OptoDesigner library, as well as HHI-specific information such as mask layer names, design rules, and GDS settings. Furthermore, this PDK contains additional side view cross-section information to enable waveguide refractive index extraction.
