The design, construction, and operational testing of a five-stage, fully interconnected 32 × 16 switching fabric by the use of smart-pixel (2, 1, 1) switching nodes are described. The arrays of switching nodes use monolithically integrated GaAs field-effect transistors, multiple-quantum-well p-i-n detectors, and self-electro-optic-device modulators. Each(More)
This paper will review some of the photonic technologies that could become important components of future telecommunications systems. It will begin by dividing photonic devices and systems into two classes according to the function they perform. The first class, relational, will be associated with devices, which under external control , maps the input(More)
A reconfigurable intelligent optical backplane architecture for parallel computing and communications is described. The backplane consists of a large number of reconfigurable optical channels organized in a ring with relatively simple point-to-point optical interconnections between neighboring smart-pixel arrays. The intelligent backplane can implement (l)(More)
We describe the design and demonstration of an extended generalized shuffle interconnection network, centrally controlled by a personal computer. A banyan interconnection pattern is implemented by use of computer-generated Fourier holograms and custom metallization at each 32 × 32 switching node array. Each array of electrically controlled tristate(More)
We describe a system demonstrator based on vertical-cavity surface-emitting lasers, metal-semiconductor-metal detectors, printed circuit board (PCB) level optoelectronic device packaging, a compact bulk optical relay, and novel barrel/PCB optomechanics. The entire system was constructed in a standard VME electrical backplane chassis and was capable of(More)
A design analysis of a telecentric microchannel relay system developed for use with a smart-pixel-based photonic backplane is presented. The interconnect uses a clustered-window geometry in which optoelectronic device windows are grouped together about the axis of each microchannel. A Gaussian-beam propagation model is used to analyze the trade-off between(More)
The design, modeling, and experimental characterization of a microchannel-based free-space optical interconnect is described. The microchannel interconnect was used to implement a representative portion of an optical backplane that was based on field-effect transistor, self-electro-optic device smart-pixel transceivers. Telecentric relays were used to form(More)
– We present the rationale, implementation and performance features of a virtual lab environment for an electronic circuits course. The primary purpose of the tool is to provide an environment that mimics some of the failure modes of a real lab, which aids the student in learning debugging techniques. The tool is implemented as a Java application. Index(More)
Introduction Building on the capabilities of the Internet, educational institutions as well as industry at all levels have moved quickly to exploit this new technology for instructional purposes. According to some industry estimates, the number of users worldwide will pass the one billion mark by 2005 (United States Internet Council, 2000). In the United(More)
A smart-pixel array is a two-dimensional array of optoelectronic devices that combine optical inputs and outputs with electronic processing circuitry. A field-programmable smart-pixel array (FP-SPA) is a smart-pixel array capable of having its electronic functionality dynamically programmed in the field. Such devices could be used in a diverse range of(More)
