Design of all-optical read-only memory

Not Accessible

Your library or personal account may give you access

Abstract

A semiconductor optical amplifier-based all-optical read-only memory (ROM) is successfully demonstrated through simulations using a one-level simplification method optimized for optical logic circuits. Design details are presented, and advantages are discussed in comparison with an all-optical ROM- employing decoder. We demonstrate that eight characters can be stored at each address in the American Standard Code for Information Interchange.
