An unexpected breakthrough in flat optics
An unexpected discovery in a Harvard lab has led to a breakthrough insight into choosing an unconventional material, silica, to make optical metasurfaces – ultra-thin, flat structures that control light at the nanoscale and are already replacing traditional optical devices like lenses and mirrors. A team from Harvard's John A. Paulson School of Engineering and Applied Sciences and collaborators at the University of Lisbon has found that in some cases, silica — the fundamental
