Abstract
Abstract Improvements are provided in electro-optical circuits and techniques for manufacturing same. Circuits are formed by depositing or otherwise providing strips or layers of light conducting material on a substrate and forming circuits thereof with electrical elements such as light emitting and light sensitive electrical devices which are formed thereon or otherwise provided in optical coupling relationship with the light conducting material.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
152 words
A method of producing an electro-optical circuit comprising: fabricating a composite article of a laminate of a substrate and a layer of light transmitting material by bonding said layer of light transmitting material to a selected portion of the surface of said substrate wherein said light transmitting material defines a flat strip-like light pipe capable of conducting light along its length, securing an electrically activated light emitting means to said composite article in optical coupling relationship with an end of said flat strip-like light pipe of light transmitting material, connecting said light emitting means to a source electrical signals defining information being processed, providing a photosensitive electro-optical transducing means in optical coupling relationship with said light pipe and securing said photosensitive transducing means to said composite article, and securing electrical interconnecting means between said photosensitive means and an output circuit for utilizing and processing the signals generated by said photosensitive transducing means.
Claim 2
Independent Claim
152 words
A method of producing an electro-optical circuit comprising: fabricating a composite article of a laminate of a substrate and a layer of light transmitting material by bonding said layer of light transmitting material to a selected portion of the surface of said substrate wherein said light transmitting material defines a flat strip-like light pipe capable of conducting light along its length, securing an electrically activated light emitting means to said composite article in optical coupling relationship with an end of said flat strip-like light pipe of light transmitting material, connecting said light emitting means to a source electrical signals defining information being processed, providing a photosensitive electro-optical transducing means in optical coupling relationship with said light pipe and securing said photosensitive transducing means to said composite article, and securing electrical interconnecting means between said photosensitive means and an output circuit for utilizing and processing the signals generated by said photosensitive transducing means.
Claim 3
Dependent Claim
23 words
A method in accordance with claim 1 including the step of forming a layer of said light transmitting material directly on said substrate.
Claim 4
Dependent Claim
