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.

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.
