Chatoyant: a computer-aided-design tool for free-space optoelectronic systems

Abstract

Chatoyant is a tool for the simulation and the 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 the bit-error rate.

MEMS design simplification with virtual prototyping

“…Dewey et al used analog hardware description languages (VHDL-AMS) for their project Visual Integrated-Microelectromechanical VHDL-AMS Interactive Design (VIVID) [38]. Often the tools were by-products from code written for the design of another specific project [39,40] and often difficult to use [41]. They appear as a collection of tools [42], sometimes limited to specific applications [43].…”

“…To simplify notation, let x = x1 and denote the left-hand side of (2) by H(x), so that (2) can be rewritten more compactly as:…”

Performance Simulation of a Microwave Micro-Electromechanical System Shunt Switch Using Chatoyant

“…Optical, electrical and mechanical components are modeled in an object-oriented language. Originally developed as an optical/electrical end to end system-level CAD tool [3,4], Chatoyant has been extended to MEMS and MOEMS modeling [5]. Systems can be designed by composing objects from the component library using a graphical user interface.…”
