Abstract

This is a multilayer opto-electronic module structure contains alternate layers of light-conducting material and light-isolating material, which are formed on a substrate and on each other. Isolating bars are formed in a predetermined pattern within layers of light-conducting material to define optical channels. Suitable illuminating and detecting means are included within the channels using optically isolating materials as electrical conductors, so as to perform logic, memory and display functions.

Monolithic Opto Electronic Structure

This is a multilayer opto-electronic module structure contains alternate layers of light-conducting material and light-isolating material, which are formed on a substrate and on each other. Isolating bars are formed in a predetermined pattern within layers of light-conducting material to define optical channels. Suitable illuminating and detecting means are included within the channels using optically isolating materials as electrical conductors, so as to perform logic, memory and display functions.

In a monolithic package shown, electroluminescent elements 1, 2 and photosensitive elements 3,4 are included in spaces formed by bars 5, 6, 7 and 8, 9, 10, respectively, and vertical isolating layers 11 to 14. Isolating layer 14 is continuous to provide a cover for the package. Intermediate metallized layers at 11, 12, 13 provide vertical optical isolation. Metal bars 5 to 10 provide horizontal isolation. Thus, optical glass channels 15, 16 are defined to provide communication between electroluminescent devices 1, 2 and photosensitive devices 3,4.

The metallized layers and bars form conductor patterns and act as electrical conductors to the outside of the structure, and thus as electrodes for devices 1 to
4.
