• Photonic Integrated Circuits and Tunable Lasers
  Technologies for Photonic Integrated Circuits (PICs) feature a large variety of complex passive and active multifunctional elements. VPIsystems experts will present design applications for novel passive integrated circuits, tunable lasers and multi-section semiconductor devices. A new family of passive PIC elements will be introduced through designs including MMIs, star couplers, and microrings resonators. Among others, designs include the modeling of carrier and tuning dynamics, birefringence, polarization coupling and dispersion effects.

• 40Gb, 100Gb and beyond: Multilevel Modulation Formats, Coherent Detection and DSP
  VPIsystems experts will discuss design aspects of 40, 100Gb/s and Terabit transmission systems. This includes options for generating multilevel modulation formats such as (D)mPSK, mQAM, and OFDM. The technological principles and performance of 1Tb/s superchannels (based on multiband OFDM, Nyquist WDM) will be illustrated. The usage of Digital Signal Processing (DSP) to mitigate impairments resulting from transmitter/receiver influences, fiber propagation, optical bandwidth and noise limitations will be demonstrated.

• Dynamic Network Reconfiguration and EDFA Transients
  VPIsystems experts will illustrate the impact of dynamic traffic changes on system performance resulting from adding/dropping and switching channels using the Transient Simulation Environment available in VPItransmissionMaker. Different control schemes for EDFA transients as well as the modeling of ROADMs will be discussed. For instance, the impact of power loops in Ring architectures will be illustrated.

• Cost-optimized Equipment Configuration
  The configuration of optical transmission links requires consideration of many trade-offs to optimize the performance while minimizing costs. The presentation shows how to capture innovations as link design rules and equipment libraries to help application engineers respond to RFQs by configuring equipment based on brown and green field requirements. Detailed customizable reports (such as system performance, BOM, equipment utilization) will be generated.

• Aggregation, Optical Access and RF-over-Fiber
  Requirements for the delivery of analog and digital services in access networks including FTTx/PON and wireless backhaul will be discussed. Predicting network performance requires modeling impairments resulting from QAM distortion ingress, SRS, SBS and others. Various examples of access topologies and high dynamic range systems will be shown, for instance the usage of reflective semiconductor optical amplifiers (RSOA) in PON-ONUs. Degradations related to the coexistence of different technologies on the same fiber infrastructure will be characterized (e.g. SRS between GPON and 10GPON or video-overlay)

• Fiber Amplifiers and Lasers
  An introduction into the theoretical background of modeling Er/Yb doped or co-doped fibers for amplification and lasing will be explored. Examples of designs for Er/Yb co-doped fiber amplifiers, cladding pumped high power lasers and pulsed fiber lasers will be presented. Automated Raman pump optimization in light of realistic fiber propagation characteristics will be discussed.

VPIsystems is pleased to present Version 8.6 of its market-leading Photonic Design Automation suite VPItransmissionMaker & VPIcomponentMaker providing many new modeling features, improved usability and advances in design process and data analysis compared to the previous version.

Version 8.6 enables a drastic reduction of simulation time thanks to new multithreading and GPU-assisted simulation of key modules and modeling functions. The new Simulation Engine Driver provides access to the simulation engine for external systems and third-party tools which allows simulations to be run and operated without the graphical user interface.

With Version 8.6 VPItransmissionMaker™Optical Systems supports more flexibly the simulation of multirate transmission systems (e.g., deployment of 112Gb/s channels on 10G legacy infrastructure), design of short-reach MMF-based MIMO transmission systems, assessment of impairments due to ADC imperfections, improved modeling of dynamic network events, and many more applications.

The new VPIcomponentMaker™Photonic Circuits allows large-scale photonic integrated circuits (PICs) to be designed, analyzed and optimized. You can build upwards from fundamental photonic elements, such as active and passive waveguides, directional couplers, branches, MMIs, star couplers and microring resonators. Among the applications are semiconductor lasers and LEDs (tunable, injection-locked, unstable), active PICs (switches, modulators, detectors), passive PICs (AWG and MMI-based MUX/DeMUX, delay lines, filters) and detailed systems modeling (impact of noise, chirp, bandwidth).

VPIlinkConfigurator is a versatile software tool for optical link engineering including automatic equipment placement and configuration and a thorough system wide performance assessment. This tool enables the rapid turnaround of network design tasks, product application requests and RFQs. In addition, uniform results, across an organization, are ensured through the use of controlled equipment libraries and link design methodologies.

Version 3.2 provides powerful link modeling capabilities using sophisticated, patented algorithms in conjunction with an easy-to-use graphical user interface. It supports equipment configuration of complex network topologies. Interconnected links are shown in a detailed two-dimensional topology display. The product's powerful link modeling capabilities ensure that designs comply with all physical layer design rules and are cost optimal, taking into account available equipment choices. Monitor points placed along the link help to extract information on goals and actual performance. Bill of Materials and performance reports are automatically created in a customizable format. A powerful API allows for virtually complete control of the link design process and performance assessment using familiar programming tools and integration with other applications.

VPIsystems supports 140+ universities and non-profit research centers around the world to simulate lab experiments, perform classroom demonstrations, and investigate new designs. The VPIsystems University Program offers academic software licensing and training discounts, flexible licensing options and course material development.

Photonics Curriculum v 6.0

With the Photonics Curriculum our partners receive a free package of course material including lecture notes and laboratory exercises for academic programs. The curriculum is designed to teach the basics of Photonics using VPIsystems modeling and analysis tools. The material consists of individual modules that are customizable and extendable. The latest version 6.0 contains 15 course modules with new laboratory exercises for VPItransmissionMaker & VPIcomponentMaker v 8.5 and higher.

Free Simulator – VPIplayer™

Sophisticated simulation setups can be exported from VPIphotonics optical equipment design suite, easily distributed as dynamicDataSheet™ (dds), and run in the free simulator VPIplayer. This empowers R&D engineers or teachers to present their ideas to colleagues, customers or students who have less specialized technical knowledge, and no need for detailed design and simulation software. VPIplayer comes with a fully featured photonic simulation engine and generates results on flexible data analyzers. Interactive settings allow adjusting parameter settings via predefined sliders.
