Abstract

In this paper we suggest objective methodology for evaluating tradeoffs between optical/digital components in a hybrid processor. This methodology is based upon signal detection theory as a means of evaluating component performance in specific tasks. Two signal detec-tion tasks are hypothesized and discussed, and we demonstrate that an assumed advantage of a digital system, precision or low-noise, is less important when realistic data sources are considered.
