In this video, we show how to use VPIlabExpert™ as part of our VPIphotonics Design Suite™ to transmit a discrete multitone (DMT, real-valued OFDM) signal through a real link accessing lab equipment like a Tektronix 70000 series AWG and a Tektronix DPO70000SX oscilloscope here. We further demonstrate how you can perform bit-and-power loading by controlling schematic runs with a Python script to increase the system capacity while ensuring a minimum performance metric for all the subcarriers.
Ksenia Goroshko, an optical engineer at VPIphotonics, explains how to mitigate fiber nonlinearities using the twin waves technique.
She demonstrates the power of this method by running an exemplary schematic in the simulation software VPIphotonics Design Suite™ for different parameter settings.
VPItransmissionMaker™ Optical Systems accelerates the design of new photonic systems and subsystems for short-range, access, metro and long-haul optical transmission systems and allows technology upgrade and component substitution strategies to be developed for existing fiber plants.
Talk from Dr. André Richter (VPIphotonics) at ECIO 2016
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.
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.
VPIcomponentMaker™Photonic Circuits is a simulation and design environment for modeling photonic integrated circuits (PICs). It provides advanced device libraries integrated with a scalable time-and-frequency-domain simulation framework enabling fast and accurate modeling of large-scale PICs with a mix of photonic, electrical and optoelectronic devices.
