Testing Hyper-complex Quantum Theories With An Exotic Metamaterial

A research team led by Philip Walther at the University of Vienna designed a photonic experiment using exotic metamaterials, which were fabricated at the University of California Berkeley. Their experiment supports standard quantum mechanics and allows the scientists to place bounds on alternative quantum theories.

Columbia Engineers Invent Method to Control Light Propagation in Waveguides

A team of Columbia Engineering researchers, led by Applied Physics Assistant Professor Nanfang Yu, has invented a method to control light propagating in confined pathways, or waveguides, with high efficiency by using nano-antennas. To demonstrate this technique, they built photonic integrated devices that not only had record-small footprints but were also able to maintain optimal performance over an unprecedented broad wavelength range.
