Analysis of an Ultra-High Speed Content-Addressable Database Retrieval System.

摘要

This work presents a model for assessing the performance of a paradigm and its implementation first proposed by Chou, Detofsky, and Louri entitled Multiwavelength Optical Content-Addressable Parallel Processor (MW- OCAPP) and its implementation as a high speed optical chip. The paradigm uses polarization states to represent binary very words and EO modulators to represent database words to perform what is essentially XOR operations. The model was created using Matlab M-files consisting of custom and built-in functions. Polarization is represented by the Jones Vectors. All polarizations are considered to be linear. Since the model only addresses the temporal characteristics of the EO modulators, transmission losses due to possible waveguide losses and insertion losses between interfacing subsystems are not considered. The grating subsystem is assumed to have a constant loss across all wavelengths which is arbitrarily set at 90% loss. The final photodector array has a linear response.
