Caltech Breakthrough Brings Fiber-Optic Performance to Silicon Chips

Caltech’s new fiber-like photonic chips achieve record-low visible-light loss, enabling more coherent lasers and next-generation quantum and sensing technologies. Caltech researchers have created a technique that allows light to travel across silicon wafers with extremely low signal loss, nearing the performance of optical fiber even at visible wavelengths. Achieving this level of efficiency on a [...]
