Going Vertical to Advance PICs

ECE Prof. John Bowers and his lab researchers have spent several decades advancing photonic integrated circuits (PICs) – and now, with Caltech and Anello photonic colleagues, they have achieved a significant breakthrough. Bowers and the researchers' work appears in the August 3 issue of the journal NATURE, in an article titled “3D integration enables ultralow-noise isolator-free lasers in silicon photonics.”
