G06E

OPTICAL COMPUTING DEVICES (digital storage using optical elements G11C13/04)

Introduced: January 1990

Description

G06E covers computing and calculating devices that use optical phenomena as the primary operational mechanism, including photonic processors and light-based logic systems. These technologies employ photons, light beams, or optical signals to perform computational functions such as arithmetic operations, data processing, and logical operations that are traditionally handled by electronic computers. Typical inventions include optical gates, photonic circuits, holographic processors, and systems using interference or diffraction for information manipulation. This subclass excludes purely electronic computing devices (G06F) and optical display or measurement instruments lacking computational function.
