Researchers from UC Berkeley published a technical paper titled “Zero-change foundry compatible silicon photonics MEMS optical switch.” Abstract Excerpt: The paper demonstrates a broadband silicon photonics MEMS switch with “more than 30 dB extinction ratio” using a “zero-change foundry compatible process and Back-end-of-Line (BEOL) post-processing.” It also reports insertion loss of “less than 1…
A new type of organic thin film manipulates light in ways not currently possible on today’s silicon photonic chips—and placing it directly onto silicon opens the door to optical components such as modulators, amplifiers, and specialized light sources for quantum technologies.
