Generalized methodology for modeling and simulating optical interconnection networks using diffraction analysis

SPICE-Based Optoelectronic System Simulation

spiceis a widely used simulation tool for electrical circuits and systems. When optoelectronic elements, such as lasers, detectors, modulators, etc., and optical elements, such as lenses, gratings, beam splitters, etc., are incorporated into spice, optoelectronic system simulation can be combined with that of electronic systems, facilitating hybrid system design and analysis. We discuss an optoelectronic spice implementation that includes time-, power-, and wavelength-domain behaviors. Examples of optical component simulation and optical interconnect system simulation by use of spice are included and compared with the results from a conventional ray-tracing optical analysis tool.

Hardware Description Language for Optical Processing (hadlop): a Simulation Environment for Parallel Optoelectronic Architectures

We present a simulation environment for parallel optoelectronic data-processing systems, and we especially consider the fusion of optoelectronic integrated circuits and optical interconnection modules. hadlop, which stands for hardware description language for optical processing, is a simulator that works at the digital design level. So far, hadlop has allowed algorithm and architecture studies for smart-pixel systems. We have just begun to extend the capabilities of hadlop toward an automatic synthesis tool for three-dimensional optoelectronic VLSI circuits. A hadlop architecture will then be the basis for the automatic generation of detailed construction plans that consider the interaction between optical interconnection modules and optoelectronic integrated circuits. The simulation system is freeware and is available through the Internet at http://www2.informatik.uni-jena.de/pope/HADLOP/hadlop.html.
