Abstract
An electro-optical system is provided for the high speed storage and retrieval of digital information. In an exemplary embodiment, the system comprises pairs of closely coupled optical waveguides, with an intervening boundary storage layer. Data may be written to the storage layer during fabrication or by an external laser process. Data is read by injecting an input optical pulse which is lightly coupled through the storage layer to the data waveguide, where it may exit as an optical pulse train. This output may be converted to electrical signals.
