CPC Definition - Subclass G06E

Last Updated Version: 2026.01
OPTICAL COMPUTING DEVICES (digital storage using optical elements G11C 13/04)
Definition statement

This place covers:

All devices in which at least one computing function is performed by optical means. Optical computer is a device that uses the light beams, rather than electric current, to perform digital or analogue computations.

Relationships with other classification places

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, e.g. G06C, G06D.

Definition statement

This place covers:

Optical computers operating not exclusively on digital data, but on analogue data or a combination of digital and analogue data (hybrid).
