Conference and Seminar Recordings

  • Scalable design of integrated photonic and optoelectronic circuits

    Talk from Dr. André Richter at PIC International Conference on 10th April 2018 in Brussels
     


    Efficient and convenient solutions for electronic photonic design automation (EPDA) present fundamental prerequisites for the fast and innovative development of next-generation integrated photonic and optoelectronic circuits. In the talk held at PIC International 2018 in Brussels (Belgium) we demonstrated how a layout-aware schematic-driven methodology enables the rapid prototyping of new design concepts, including parameter optimization of photonic and electronic parts, analysis of manufacturing tolerances, and comparison of technology and integration alternatives to highlight progress in this area.

  • Mastering challenges

    The NGON US team interviewed Jim Farina, director of technical services at VPIphotonics™ – he spoke about VPIphotonics, the key challenges the company is currently facing, his opinion on the state of the North American market, and also the importance of events like Next Generation Optical Networking for the industry as a whole.

  • eSeminar with CST and VPIphotonics

    Design Optimization and Sensitivity Analysis of Photonic Integrated Circuits using Physical and Circuit-Level Simulations


    The use of highly-integrated photonic circuits (PICs) is on the rise, and this trend is expected to accelerate in the future.
     
    The design of these complex circuits involves multiple steps, starting at the component level and continuing up to the circuit level. Due to this hierarchical structure, small variations at the component level resulting from fabrication tolerances can have a significant influence on the overall circuit performance.
     
    This eSeminar focuses on two software packages, which combine advanced simulation of passive photonic, active optoelectronic and hybrid photonic integrated circuits and systems with highly accurate full-wave 3D photonic and multiphysics simulation.
     
    We will demonstrate how using VPIphotonics Design Suite and CST Studio Suite together enables engineers designing PICs to automate combined circuit level and full wave simulation. This allows the study of the effect of small variations in the components on the overall circuit, meaning that the engineer can increase yield and reliability by making the circuit resilient to such effects.
