VPItoolkit™ PDK HHI

VPItoolkit PDK HHI is a pluggable toolkit which extends VPIcomponentMaker Photonic Circuits by adding the support of the InP photonics Process Design Kit (PDK) for the Multi Project Wafer runs offered by the Fraunhofer Institute for Telecommunications, Heinrich Hertz Institute, HHI.


It enables the rapid design of Indium Phosphide monolithically integrated passive and active photonic circuits for their subsequent fabrication at the HHI Photonic InP Foundry.


VPItoolkit PDK HHI supports export of layout for designed circuits to PhoeniX OptoDesigner by Synopsys, IPKISS by Luceda Photonics and Nazca Design. All of these layout design tools can also be used for a seamless GDS mask generation.

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.
