Article
We report on architectural requirements for an avionics WDM network, proposed reference architecture, metrics required from modeling and simulation, and physical-layer simulation studies of this reference architecture
Conference Paper
Free space optics (FSO) is widely regarded as the next-generation high-speed wireless communication technology, and due to the security and high data rates is being considered for military systems. The availability of simulation tools for FSO systems may help in engineering trade-off and optimization studies, in shortening the design-to-deployment...
Conference Paper
The OCDMA techniques have been studied for various networking applications including LAN, access networks and all-optical GMPLS-based packet switching. Unlike RF-CDMA, the OCDMA codes need to have minimal cross-correlation properties due to the IM/DD nature of the data links. In this paper, we describe the design of multi-user high-speed networks w...
Conference Paper
The physical-layer design of optical interconnects for box-to-box, backplane, intra-board, and intra-chip applications must address a number of considerations including system performance, manufacturing yield, reliability, power consumption, thermal properties, and cost. Also, there are multiple levels of abstraction and domains over which optical...
Conference Paper
This paper describes the disadvantages of spreadsheet-based analysis for high-speed multimode systems and presents multimode system simulation as an alternative. An example is depicted in which the system power margin calculated by the spreadsheet model was overly pessimistic relative to that predicted by system simulation. The higher degree of acc...
Conference Paper
This paper describes a new multimode fiber model specifically geared toward system-level analysis. The model numerically solves for the fiber modes as a function of an arbitrary index profile. This is a level detail usually found only in device-level models. Since it is implemented in a general-purpose tool, it is extremely flexible and capable of...
Conference Paper
The recent wide-spread deployment of gigabit, multimode, optical data links has led to the need for better design methodologies to both lower cost and improve performance. One of the most critical performance predictors for these systems is the bandwidth of the multimode fiber used in the link. We have demonstrated, through an integrated device/sys...
Article
In high-speed, multimode-fiber-based data-communication applications, modal dispersion is often the performance-limiting factor. Traditionally, system-level simulations neglect spatial effects for computational efficiency while device-level tools involve computations too complex to perform system-level analysis. In this paper, we have combined the...
Article
Computer-aided-design tools model fiberoptic telecommunications components at a variety of different levels of abstraction. Simulators at different levels of a hierarchy can be used together to tie design parameters at one level more closely to performance at another level.
Conference Paper
Accurate modeling of photonic devices is essential for the development of new, higher performance optical components required by current and future high-bandwidth communication systems. This paper reviews one of the predominant techniques for such modeling, the beam propagation method (BPM), and describes several applications along with experimenta...
Conference Paper
The different polarisation mode dispersions (PMDs) under consideration include combinations of wavelengths at 850 nm, 1310 nm, and 1550 nm with either serial transmission or a coarse 4 channel WDM transmission operating on either multimode fiber or single mode fiber. Modeling and simulation are important tools in evaluating the various PMDs under c...

Experience with commercial and research high-performance architectures has indicated that the compiler plays an increasingly important role in real application performance. In particular, the difficulty in programming some of the so-called "hardware first" machines underscores the need for integrating architecture design and compilation strategy. I...
Article
Optoelectronic components and lightwave systems continue to rapidly advance in capabilities and complexity. CAD tools must also advance to meet the needs of the advanced lightwave systems of tomorrow. As integrated CAD tools are available for the hierarchical design of electronics systems, CAD tools for optoelectronics and lightwave systems must al...

The Optoelectronic Technology Consortium (OETC) 16 Gbit/s, 32-channel parallel fiber optic bus introduces new requirements for modeling and simulation of an optical bus which were not present for previous single-channel optical link systems. These requirements include the simulation of the statistical variation in component parameters, timing skew,...
Conference Paper
Full-text available
This paper discusses the present state of the art of components, systems, and application technology related to parallel optical data links (ODL) as demonstrated by the OptoElectronic Technology Consortium (OETC). Parallel ODL technology is poised for large volume commercialization despite some uncertainties in industrial standards and system appli...
Conference Paper
The modeling and simulation of the Optoelectronic Technology Consortium's optical bus and the treatment of the unique requirements for the modeling of a synchronous optical bus is presented. Simulation results are compared to experimental measurements and conclusions drawn
Conference Paper
Computer aided design (CAD) tools prepare for an expanded role in the design of fiber-optical systems for high-performance computing and communications systems. One crucial part of the design of CAD tools is the efficient modeling of the optoelectronic components and the accurate prediction of the optical pulse deterioration along the optical link....
Article
The computer-aided design tool can be used in choosing design parameter values that help lower the cost and increase reliability. Good tools are also necessary to minimize the length of the design cycle to bring products to market in a timely manner. Some tools exist that can be used for simulating and designing optical interconnects, but they are...
Article
Optical interconnects play an increasingly important role in high-performance computing and communications. Computer-aided design (CAD) tools are essential for performance analyses and component specifications for optical interconnects. This paper discusses circuit- and system-level models and simulation methods for optical interconnects consisting...
Conference Paper
Summary form only given. We have developed a mixed-level simulation environment by integrating a new system-level optical link simulation tool with a circuit-level simulation tool to provide a simulation environment that can be used to efficiently optimize component parameters in an optical interconnect. The optical link simulation is driven by the...
