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

New fabrication method speeds up production time for photonic chips via parallel processing technology However, translating that potential into mass-producible hardware is often bottlenecked by slow, complex manufacturing. A Chinese research team says it has overcome one of the field’s biggest manufacturing hurdles, unveiling a fabrication method that cuts production time for complex three-dimensional optical structures from hours to seconds. “Our work establishes a versatile platform that bridges the gap between design complexity and scalable manufacturing for next-generation 3D integrated photonics,” wrote the research team led by PhD student Wang Yi.
