Optical computing is a technology that uses light instead of electricity to perform calculations and process information. By utilizing photons, which are particles of light, optical computers can potentially operate at much higher speeds and with greater efficiency than traditional electronic computers. This approach can lead to faster data transmission and reduced energy consumption. In optical computing, components like lasers, optical fibers, and photonic circuits are used to manipulate light signals. Researchers are exploring various applications, including quantum computing and advanced data processing, to harness the benefits of light-based systems in computing and communication technologies.
