Paper Abstract

The need for high performance A/D converters, the advantages of optics, and current approaches to A/D conversion are reviewed. A novel method is proposed that uses comparators, optical logic, and a table look-up to provide optical digital output from an optical analog input. The advantage of the new method is the ability to produce any digital code, optical input/output, and longer word lengths at high speed. Implementations of the optical logic are proposed that use 1-D SLM devices under development. The optical A/D could make digital multiplication by analog convolution competitive with electronic systems.
