Columbia Engineering Professor Nanfang Yu has invented a method to control light propagating in confined pathways, or waveguides, with high efficiency by using nano-antennas. He built photonic integrated devices that had record-small footprints and were also able to maintain optimal performance over an unprecedented broad wavelength range. His method could lead to faster, more powerful, and more efficient optical chips, which in turn could transform optical communications and optical signal processing. (Nature Nanotechnology 4/17)
