Will there ever be a chip that uses light instead of electrical current? Is it even possible?

Will there ever be a chip that uses light instead of electrical current? Is it even possible?
Between optical chips and large scale chips like the Cerebra's large-scale chip could this change the whole game as far as size and location of data centers and even bring that power to offices and the home cutting the demand for data centers in the future by as significant amount?The idea of using light instead of electricity to power computer chips is moving from science fiction to reality. Photonic chips, or optical processors, transmit information using photons rather than electrons. Because photons travel at the speed of light and produce virtually no heat, they promise enormous gains in speed and energy efficiency. Instead of metal wires, these chips use waveguides to steer light, modulators to encode data, and photodetectors to read signals.
Companies such as Intel, IBM, Ayar Labs, and Lightmatter are pioneering silicon photonics—integrating optical components with traditional transistors. These hybrid systems are already used in data centers to accelerate communication and reduce power consumption. Researchers are also experimenting with purely optical logic systems capable of performing computations through light interference, potentially transforming AI and supercomputing.
