This paper presents Chatoyant, a tool for simulation and analysis of heterogeneous free space optoelectronic architectures. It is capable of modeling digital and analog electronic and optical signal propagation with mechanical tolerancing at the system level. We present models for a variety of optoelectronic devices, and results that demonstrate the system’s ability to predict the effects of various component parameters, such as detector geometry, and system parameters, such as alignment tolerances, on system performance measures, such as bit error rate. 1.

A tool for computer-aided design and simulation of digital 3-D optoelectronic computing systems is presented. The program especially considers the features offered by the optics. The usefulness and the large flexibility of the tool was demonstrated exemplary for both architecture proposals published in literature and own proposals. The simulation system is freeware and is available via the Internet http://www2.informatik.uni-jena.de/ pope/HADLOP/hadlop.html. 1 Introduction: The necessity of design tools in optoelectronic computing Recent advances in the development of active and passive devices for optoelectronic computing [1, 2, 3] make the use of high dense optical interconnections in the chipto -chip area more and more likely. The increasing availability of fine-grain optoelectronic integrated circuits (OEIC) - with a high number of parallel optical input/output (I/O) channels - promises to overcome one of the major problems in today's very large scale integrated circuit (VLSI) tec...

this paper. The necessity of CAD tools and models that explicitly consider optics has already been realized by other research groups.

The use of MEMs technology has enabled the fabrication of micro-optical and micro-electro-mechanical systems on a common substrate. This has led to new challenges in computer aided design of optical micro-electro-mechanical systems. We have extended our opto-electronic system CAD tool, Chatoyant, to attempt to meet the needs of optical MEMS designers. This paper presents new component models and analysis techniques which extend our tool to support optical MEMS design. We demonstrate these extensions with the analysis of a micro-optical high speed FFT engine and a 1x2 optical MEM interferometer switch. Keywords: MEMS-CAD, optical MEMS, MOEMS, micro-optics 1. INTRODUCTION Applications for optical MEMS (micro-electrical-mechanical systems) are growing to include scanning, projection, display, switching, printing, sensing, modulating, and data storage. 24 As these applications are quickly evolving from abstract ideas to marketable products, it is essential to have CAD tools to model t...

Chatoyant models free-space opto-electronic components and systems and performs simulations and analyses that allow designers to make informed system level trade-offs. Recently, the use of MEM bulk and surface micro-machining technology has enabled the fabrication of micro-optical-mechanical systems. This paper presents our models for diffractive optics and new analysis techniques which extend Chatoyant to support optical MEMS design. We show these features in the simulation of two optical MEM systems. Keywords: Optical MEMS, MEMS-CAD, MOEMS, micro-optics
