CPC Definition - Subclass G06E
This place covers:
All devices in which at least one computing function is performed by optical means.
This place does not cover:
Optical logic elements per se | |
Computer systems based on specific computational models | |
Digital storage using optical elements |
This technology is hardly used anymore.
Optical computers were a technology that was popular between 1900 - 2000.
After 2000 there are virtually no patent applications in this field anymore.
If other aspects, for example mechanical, fluid pressure or electrical computing, are of interest, classification is also made in the relevant subclass for such aspects.
This place covers:
Optical computers working exclusively on digital data.
This place does not cover:
Optical logic elements | |
Electronic digital computers | |
Optical digital storage |
Attention is drawn to the following places, which may be of interest for search:
Quantum computers |
Documents should be classified in the subgroups of G06E 1/00 only if they deal with purely digital optical computing.
This place covers:
Optical computers operating not exclusively on digital data, but on analogue data or a combination of digital and analogue data (hybrid).
This place does not cover:
Optical logic elements | |
Electronic digital computers | |
Analog electronic computers | |
Hybrid non-optical computing devices | |
Optical digital storage |
Attention is drawn to the following places, which may be of interest for search:
Quantum computers |
Documents should be classified in the subgroups of G06E 3/00 only if they deal with purely optical computing on a combination of digital and analogue data or on analogue data only.
