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 1.5 dB”... » read more The post Silicon Photonics MEMS-based Optical Switch Using a Zero-Change Foundry–Compatible Process (UC Berkeley) appeared first on Semiconductor Engineering .
