Integrated optical computing

Definition

Integrated optical computing refers to a technology that combines optical components and electronic circuitry on a single chip to perform computations using light instead of electricity. This approach allows for faster data processing and lower power consumption, as light signals can carry more information than electronic signals. The integration of optics and electronics opens up new possibilities for parallel processing, which can significantly enhance computational speed and efficiency.
