Abstract :
The Scottish Collaborative Initiative in Optoelectronic Sciences (SCIOS) is developing an optoelectronic parallel sorter using CMOS/InGaAs hybrid technology. We describe the design of a system with the potential of sorting 1024 8-bit words in 10 μs. The system is based on 32-by-32 arrays of smart pixels produced by solder-assembly of strained InGaAs/GaAs MQW modulator/detectors with CMOS electronics. These devices are linked by an optical perfect shuffle interconnect. The functionality of each processing node, as required by the algorithm, is selected by optical control signals which are circulated along with the optical data. Various physical constraints, including optics limitations, laser power requirements and heat dissipation, have been investigated
