  • Design of hybrid Photonic Integrated Circuits combining functions in Indium Phosphide and Silicon Nitride technology

    LioniX International team with its software partners VPIphotonics and Phoenix Software demonstrates how through access to an open Process Design Kit (PDK) hybrid technology PICs, such as a tunable ultra narrow linewidth laser module, can be created. Highlights are presented of how VPIcomponentMaker Photonic Circuits extended by VPItoolkit PDK LioniX is used for circuit-level simulation, parameter optimization and tolerance analysis of multi-technology PICs.

    The product presentation takes place on Tue 30 Jan 2018, 3pm to 3:30pm in Hall D North (Demo Area 2), and is given by Douwe Geuzebroek (LioniX International).

Abstract: We report about our recent work performed in the PolyPhotonics Berlin consortium, which targets to establish a new versatile integration platform combining polymer with Indium-Phosphide and thin-film filter based technologies for numerous photonics applications in the global communications and sensing market. We present our methodologies for modelling and prototyping optical elements including hybrid coupling techniques, and compare them with exemplary characterization data obtained from measurements of fabricated devices. We demonstrate how the seamless integration between photonic circuit and layout design enables the rapid and reliable virtual prototyping of complex photonic components and integrated circuits.

Automated Design of Add/Drop Equipment and Effective Wavelength Assignment in Complex DWDM Networks

Poster Session, Paper 10560-29 – Wed 31 Jan 2018, 6pm to 8pm

D. Khomchenko, D. Yevseyenko, J. Farina, A. Richter (VPIphotonics)

Abstract: We demonstrate an algorithmic approach that offers an efficient way of assigning wavelengths and add/drop equipment. It permits for building the cost-optimized design of optical networks taking into account available (R)OADMs and transceivers, traffic demand characteristics, network topology and engineering constraints. Methods for selecting and provisioning add/drop equipment are employed. Our approach is flexible enough to accommodate optical network topologies of different types and provide add/drop equipment configuration for either a newly designed WDM network or networks being upgraded to accommodate traffic demand growth. The result is a cost-optimized configuration with effective wavelength utilization
