VPIphotonics at OFC/NFOEC 2008

Come and visit us at Booth 2925!

• Feature Presentations
• VPIlinkConfigurator v 2.5
• VPItransmissionMaker & VPIcomponentMaker v 7.6
• Project "VPI-100"
• University Program

• Multilevel Modulation Formats and Coherent Detection
  VPIsystems experts will discuss design applications for multilevel modulation formats including phase-shift keyed (MPSK), quadrature amplitude modulation (QAM) and orthogonal frequency division multiplexing (OFDM) using coherent detection.

• Dynamic Network Reconfiguration and EDFA Transients
  By means of the new Reconfigurable Optical Add-Drop Multiplexer (ROADM) module VPIsystems experts will illustrate the impact of dynamic traffic changes on system performance from adding/dropping and switching channels. Control schemes for EDFA transients will be discussed.

• Reflective Semiconductor Optical Amplifier
  VPIsystems experts will demonstrate the modeling of an optical network unit (ONU) using a reflective semiconductor optical amplifier (RSOA) in Passive Optical Networks. Modules that perform data type and boundary condition conversion are applied to allow the integration of modules from VPItransmissionMaker WDM and VPIcomponentMaker Active Photonics.

• Optical Access and Radio-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, SBS and others. Various examples of access topologies and high dynamic range systems will be shown.

• Electronic Equalization
  Requirements for robust and cost-effective WDM networks drive the demand for electronic pre-compensation and equalization (e.g., FFE-DFE, MLSE). VPIsystems experts will demonstrate performance advantages of different techniques in light of impairments from fiber propagation, bandwidth and noise limitations.

• Raman Amplifiers and Doped-Fiber Applications
  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 Er doped pulsed fiber lasers will be presented. Automated Raman pump optimization in light of realistic fiber propagation characteristics will be discussed.

• Semiconductor based Lasers and Amplifiers
  A high degree of flexibility in adapting model characteristics and accurate numerical techniques are required to predict the complex nonlinear dynamics of multi-element active photonic circuits and lasers over wide optical bandwidths. VPIsystems experts will demonstrate design applications for integrated tunable lasers, high-power lasers, ultra-fast sources, optical switches, edge detectors, wavelength converters and regenerators.

VPIlinkConfigurator is a versatile software tool for automatic optical equipment configuration, allowing engineering to respond more easily to network design tasks, product application requests and RFQs.

Version 2.5 provides powerful link modeling capabilities using sophisticated, patented algorithms in conjunction with an easy-to-use graphical user interface. Monitor points placed along the link help to extract information on goals and actual performance in either graphical or numeric format. Bill of Materials and performance reports are automatically created in a customizable format. Version 2.5 offers an enhanced Application Programming Interface to import custom-build equipment characterization and synthesis routines, and a simple method for sharing designs and libraries (with or without encryption) between co-workers and with customers. Further on, the link equipment display can be toggled between compact and expanded view, which reveals the internal architecture of composite items.

VPIsystems is pleased to present Version 7.6 providing mainly improved usability, design process, and data analysis advances compared to the previous version.

Within the new features of Version 7.6 is the new LinkAnalyzer module which works as an interface to the VPIphotonicsAnalyzer and displays tracked signal characteristics along the link (such as power, dispersion etc.) versus length or frequency.

Futhermore, several application examples have been added that demonstrate the use of RSOAs in PON networks, ROADMs and EDFA transients, OFDM and multilevel modulation in high speed systems with coherent detection.

The purpose of the VPI-100 project is to develop new modeling functions enabling the analysis, design and optimization of next generation transmission systems with data rates of 100Gbit/s and beyond. VPIsystems experts will discuss modeling constraints and development plans related to this project.

VPI-100 is part of the Celtic initiative "100-GET" (100 Gigabit Ethernet Transport Technologies).

VPIsystems supports 130+ 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 4.0

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 reworked and updated version 4.0 contains 14 course modules with new laboratory exercises for VPItransmissionMaker & VPIcomponentMaker v 7.5 and beyond.

Free Simulator – VPIplayer^TM

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.
