Photonic Hypercrystals Are Now a Reality and Light Will Never Be the Same

Recently theorized and already realized, photonic hypercrystals will further enable technologeis from Li-Fi to Solar Cells Image: National Academy of Sciences In 2014, researchers   predicted the theoretical existence of a strange new material that altered the interaction between light and matter. The material, dubbed photonic hypercrystal, has now become a reality. Researchers at the City College of(…)

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(…)
