We present an optoelectronic-VLSI system that integrates complementary metal-oxide semiconductory multiple-quantum-well smart pixels for high-throughput computation and signal processing. The system uses 5 3 10 cellular smart-pixel arrays with intrachip electrical mesh interconnections and interchip optical point-to-point interconnections. Each smart pixel is a fine grain microprocessor that ex...

This paper presents a systematic approach to design CMOS chips with concurrent picture acquisition and processing capabilities. These chips consist of regular arrangements of elementary units, called smart pixels. Light detection is made with vertical CMOSBJTs connected in a Darlington structure. Pixel smartness is achieved by exploiting the Cellular Neural Network paradigm [1], [2], incorporat...

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) dynamically reconfigurable connections...

We present a novel architecture for an optical network, TRANslucent Smart Pixel ARray (TRANSPAR), having smart pixel devices which effectively function in an optically translucent manner. The network protocol is similar to carriersense multiple-access/collision-detection (CSMA/CD) commonly used in Ethernet, but adapted to a ring configuration using optical parallel packets in free space. The TR...

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 window size, window density, transisto...

The technical issues involved in applying vertical-cavitysurface-emitting lasers (VCSEL's) to parallel opticalinterconnection systems are discussed from the viewpoint of theirapplication to asynchronous transfer mode switching and parallelcomputer systems. We also discuss approaches to designing a VCSELarray structure for high-speed modulation and the effect ofpixel-performance homogeneity on t...

High quality image transmission through smart devices requires high transmission rate, throughput and low Bit Error Rate (BER). At the same time, energy efficiency is always the top issue for the battery-based smart devices such as smart phone, iPad, etc. In this paper, an adaptive Forward Error Correction (FEC) coding and cooperative relayed image transmission system is proposed, through which...

We describe a smart-pixel circuit that permits the use of a GaAs/AlGaAs multiple quantum well diode to be used both as a detector for data input and a modulator for data output. The module provides the ability to double the number of inputs or outputs to the array and is well suited to cascaded optoelectronic system architectures that require bidirectional communition.
