China team cuts 3D optical chip production time from hours to seconds

A research team led by the Institute of Physics under the Chinese Academy of Sciences (CAS), with the University of Hong Kong, has developed a fabrication method that reduces production time for complex 3D optical structures from hours to seconds. The study, published in Advanced Materials on July 4, was led by PhD student Wang Yi. The team stated their work "bridges the gap between design complexity and scalable manufacturing" for 3D integrated photonics.
