Advances in optical interconnection technology create the potential of constructing three-dimensional systems. This has a profound impact on the performance of the designs implemented in such a way. using the average interconnection length and the interconnection length distribution as performance measures, we will show that three-dimensional architectures are much more suitable for the implementation of massivelyparallelprocessing systems than traditional two-dimensional architectures. For opto-electronic three-dimensional architectures, we have to take into to account the physical and geometric differences between optical and electrical channels. The main consequences of these differences on system performance will be discussed.

Independent of the improvements in speed of current available microprocessors, the ever increasing demands for more computing power require a massivelyparallelprocessing system that consists of multiple nodes. How opticalprocessing and optical networking shall overcome the limitations of conventional electrical interconnect topologies in future massivelyparallelprocessing systems is discussed.

A GByte/sec-class optical interconnection subsystem for a parallel computer was developed, and it operated stably in the testbed system of a parallel computer, Real World Computer-1 (RWC-1). Although it consisted of MMF parallel links, data was transmitted over 1 km because of deskew operation of +/- 15 ns. Random packets were transmitted without error over 17.5 hours, corresponding to a BER of 10(-14).

A new interconnection network for massivelyparallel computing is introduced. This network is called a Hierarchal optical Ring INterconnection (HORN). HORN consists of a single-hop, scalable, constant degree, strictly non-blocking, fault-tolerant interconnection topology that utilizes Wavelength Division Multiple Access ( DMA) to provide better utilization of the terahertz (THz) bandwidth offered by optics. The proposed optical network integrates attractive features of hierarchical ring interconnections, e.g., simple node interface, constant node degree, better support for locality of reference, fault-tolerance, with the advantages of optics. This paper presents the HORN topology, analyzes its architectural properties and presents an optical design methodology for it. Furthermore, a brief feasibility study of HORN is conducted. The study shows that the topology is highly amenable to optical implementation using commercially available optical elements.

A versatile polymeric waveguide technology is proposed for massivelyparallelopticalinterconnections. We developed a variety of low-loss high-thermal-stability polymeric materials and used them in the fabrication of complex point-to-point opticalinterconnections with controlled numerical aperture (NA) and geometry. Conventional mask photolithography as well as maskless adaptive laser-based techniques were used to produce at low cost various integrated optical devices and circuits on diverse rigid and flexible substrates. Practical applications include high-speed high-density massively-parallel on-chip, chip-to-chip, on-board, board-to-board, and backplane interconnections.

optical interconnection technologies (OITs) are expected to play an important role in alleviating the technologically induced architectural and algorithmic compromises that have to be made in the design of high-performance, massivelyparallel processors (MPPs) and their target applications. The vast diversity and relative immaturity of the OITs that have been put forth, however, point to the need for a well-articulated strategy for their inclusion into the design methodology of these systems. In particular, a broad-based study that would categorize OITs according to those architectural and algorithmic paradigms they would most impact is required. To this end, this paper presents the structure of the Applications-Driven optical Interconnect Technology (ADROIT) modeling framework and summarizes on-going work geared toward its full development.

A group at Heriot-Watt University has been working on the application of optical techniques to digital information processing. In a search for higher system performance, hybrid optoelectronic devices and, currently, silicon-based smart pixel technology, have been used at an operating wavelength of 1-1.1 μm. The group's smart-pixel technology is comprised of InGaAs QCSE-modulators/detectors, solder-bump connected to CMOS processing nodes. Input and interconnect optics exploit diffractive optics extensively. The group's work concentrates on the use of nonlocal optical interconnects between 2D processing arrays with high pin-Hz performance, reaching beyond the capability of pure electronic configurations.
