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

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 systems 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.

Modeling free space optoelectronic interconnects

This paper presents a system level optoelectronic CAD tool, Chatoyant, which has been developed to meet the needs of mixed technology systems designers. We introduce component models and analysis techniques that enable our tool to support optoelectronic interconnect system design. We demonstrate these results with the analysis of two optoelectronic interconnection systems: a multi-channel high-speed link and a 1/spl times/2 optical MEM interferometer switch.

Smart Optical Transceiver Architecture with Dynamic Channel Encoding

In this paper we introduce a novel dynamic channel coding technique designed to minimize errors introduced by electrical noise in the driver and receiver circuits and by channel-to-channel crosstalk in the optics.
