Team Develops Laser Printer for PICs
SEATTLE, Feb. 12, 2024 — The development of photonic integrated circuits (PICs) is an expensive and time-consuming process. Nanofabrication facilities cost millions of dollars to construct and are well beyond the reach of many colleges, universities, and research labs. For those who can access a nanofabrication facility, at least a day must be reserved for the exacting and time-consuming lithographic process used to make these microchips. On top of that, if an error is made in design, or if the chip doesn’t
