VPItoolkit™ PDK HHI

VPItoolkit PDK HHI is a pluggable toolkit to VPIcomponentMaker Photonic Circuits which supports InP photonics PDK for Multi Project Wafer runs offered by the Fraunhofer Institute for Telecommunications, Heinrich Hertz Institute, HHI.


The toolkit provides a library of photonic devices (see figure right) which covers most of the building blocks (BBs) currently supported by the HHI Process Design Kit.


VPItoolkit PDK HHI supports PhoeniX OptoDesigner by Synopsys as layout design tool.

Flat-top filter based on ring-loaded unbalanced MZI structure


Resonance effects provided by two Mach-Zehnder Interferometer (MZI) structures: an unbalanced and a ring-loaded MZI are superposed to produce a high-order flat-top passband transfer function.
