  • VPIphotonics Design Suite™ v10.0 + VPItoolkits™

    live demos, overview of new features

  • New Version: VPItoolkit™ PDK HHI v3.1

    Added export of circuit layout to Nazca Design

    VPIphotonics announces release of an updated version of VPItoolkit PDK HHI, which supports the InP photonics Process Design Kit (PDK) offered by the Fraunhofer Institute for Telecommunications, Heinrich Hertz Institute, and seamlessly integrates Photonic Integrated Circuit (PIC) simulation and automated mask layout extraction.

    The free and open-source Nazca Design framework developed by BRIGHT Photonics is now fully supported for the generation of verified PICs layouts to be submitted and processed in terms of Multi-Project Wafer (MPW) runs on the HHI Indium Phosphide technology platform. Similar mask export capabilities with OptoDesigner developed by PhoeniX Software (part of Synopsys) have already been introduced earlier.

  • Workshop on Hybrid PICs (WS05)

    Sunday, Sep-22, 14:00 - 17:30, Hall 7
    "PDK-enabled layout-aware circuit design and system validation" – presented by A. Richter

    Hybrid integrated photonics attracts significant attention, as it enables complete and cost-efficient optical chip solutions for silicon, silicon nitride, and polymer photonics in combination with III-V active optoelectronic devices. We discuss design challenges of hybrid PICs and present a workflow addressing them, which relies on standard simulation compact models and a layout-aware design approach. We demonstrate flexible optoelectronic circuit simulation, optimization and analysis, as well as performance verification on system-level.

  • Networking: VPIphotonics Get-Together in the Berlin Pavilion

    Tuesday, Sep-24, 15:30, Exhibition Floor – Booth 54
    We cordially invite you to visit our booth for drinks and snacks!

  • Hackathon

    Tuesday, Sep-24, 16:30 - 18:00, Hibernia Rooms

    Meet our simulation experts at ECOC's Hackathon. This year we will present how VPIlabExpert can be a useful tool in automating test and measurement setups for long simulation runs and system optimization. Demodulation of coherent QAM and probabilistically shaped signals will be shown, highlighting how Python-based DSP algorithms can be integrated in a simulation environment.

    There will also be plenty of time for mingling and discussion. Light food and drink will be served.

Professional Services and R&D Activities

Learn more about VPI's Consulting and R&D activities! Contact us for custom design services, and training seminars on modern technologies and their adequate modeling.

VPIphotonics partners with public research institutes, industry and universities to develop advanced solutions for the design and optimization of future photonic networks. These activities range from component design to network planning.


  • InPulse - Indium-Phosphide Pilot Line for up-scaled scaled, low-barrier, self-sustained, PIC ecosystem

    InPulse Pilot Line is an EU funded project that democratizes access to industrial prototyping and pre-production of high-performance InP photonic integrated circuits (PIC).

    InPulse provides a low entry barrier access to low and medium production volumes of InP PICs.

    InPulse has the ambition to transform business practices from vertical integration – where design, fabrication and product development are all in-house and inaccessible to new entrants, to horizontal where fabless and lab less businesses share the same manufacturing infrastructure.


  • SENDATE-FICUS - Secure networking for a data center cloud in Europe –
    Flexible infrastructure for data center communication providing unique security

    VPIphotonics teams up with Coriant and academic partners in the framework of the Celtic-Plus project SENDATE-FICUS.

    The purpose of this project is the development of new technologies enabling the transition from today's networks to robust, efficient, secure and re-configurable converged communication networks.


  • QAMeleon - Sliceable multi-QAM format SDN-powered transponders and ROADMs Enabling Elastic Optical Networks

    VPIphotonics' core technical contribution to the project will be in work package "Component and System Specifications and Requirements". The team will participate in formulating the project's use-cases, network requirements and performance indicators, defining the system and component specifications, as well as take an active role in the development of the TRx DSP algorithms that are central to the QAMeleon's technological objectives. VPI leads a task where system and component modeling and simulation takes place.

    The work that will be carried out here will constitute the first verification of the project's proposed system concepts. Heavy interaction with work packages related to components fabrication will take place to aid the design and development cycle, and ensure that performance targets are met. Furthermore, VPI will also actively support the experimental verification effort, contributing with researchers, as well as its commercial lab automation software (VPIlabExpert), in the laboratory and field trial validations of the developed technology.


  • EU Quantum Flagship Project UNIQORN - advances the next generation of quantum communication systems

    The multidisciplinary project UNIQORN will develop under the participation of VPIphotonics quantum technology for the mass market. Quantum communication systems, mostly found in research laboratories, will be squeezed into small and reliable photonic integrated circuits.

    By carefully laying out each element along the development chain from fabrication to application, the Horizon 2020 project will not only reduce size and cost, but will also bring improvements in terms of robustness and reproducibility.


  • PolyPhotonics Berlin - Optical Components from Plastic

    VPIphotonics teams up with regional enterprises and research institutes in frame of PolyPhotonics Berlin, an R&D project co-financed by the German Federal Ministry of Education and Research (BMBF). The PolyPhotonics Berlin consortium targets to establish a new versatile polymer based integration platform combined with Indium-Phosphide and thin-film filter technologies for numerous photonics applications in the global communications and sensing market.

    VPIs role in this initiative is to develop a toolbox of simulation models representing libraries of photonic and optoelectronic building blocks. This toolbox may serve as basis for project partners and external users when designing and verifying complex photonic components and integrated circuits that are to be manufactured by the PolyPhotonics Berlin consortium.
