Paper Abstract

Within digital memory applications, laser scanners are used to either write information on a medium or to interrogate a medium. It is our intent to address the issues of reading high volume optical mediums of digital information at nanosecond random access speeds. Current applications include digital opto- electronic computing, parallel readout of optical disk, volume holographic memory readout, as well as some of the more conventional applications such as robotic vision systems and inspection systems.

High speed digital memory (ECL,GaAs) currently used in high performance computer technologies rely on expensive and power consumptive memory chips. These memories provide only marginal densities per chip (4-l6Kbit). However, through the integration of optical interconnects and volume storage technologies coupled with alternative GaAs structures, an increase in speed as well as a decrease in power consumption can be realized. Thus, increased storage densities and faster access rates can be achieved. The laboratory prototype discussed in this paper has demonstrated that random beam deflection in the nanosecond regime is possible using tunable laser diodes and a dispersive medium.
