Free-space optical bus architecture

Linda Susan Draper, University of Texas at El Paso


Multiple processor computers require interconnection networks for inter-processor and inter-memory communications. A common interconnection network is the computer bus. Traditional electrical buses have limited speed and bandwidth. Optical buses increase the potential for throughput by enabling pipelining of communications, increased bandwidth and, possibly, increased speed of communications. Two optical bus communities (fiber-based and free-space) exist side by side with little overlap. ^ This thesis proposes a reasonable architecture for a Free-space Optical Bus (FSOB). This architecture bridges the two worlds of fiber-based and free-space-based research. An Architectural Framework Model (AFM) is proposed as a consistent method of describing an architecture. The AFM is used in the development of the FSOB architecture. This architecture addresses the following concerns: necessary physical volume, speed increase and potential increase of bandwidth. The proposed architecture is assessed and evaluated to show that this bus architecture can be configured to exceed the requirements of fiber-based optical buses. ^
