Integrated Photonic Circuits Shrunk Down to the Smallest Dimensions Yet

Integrated photonic circuit development compared to going from vacuum tubes to semiconductor transistors Illustration: Nanfang Yu/Columbia Engineering In a major breakthrough for optoelectronics, researchers at Columbia University have made the smallest yet integrated photonic circuit. In the process, they have managed to attain a high level of performance over a broad wavelength range, something not previously achieved. The(…)
