New technology enables light to be stored, delayed, and controlled within a single photonic chip, with potential applications in low-power optical computing for AI servers and next-generation optical communication systems. Light moves quickly enough to transmit enormous amounts of information, but that speed creates a problem when a computer needs to hold, delay, or synchronize [...]
