Metasurface Added to Photonic Chip to Improve Footprint, Control

Facebook X LinkedIn Email
A team of researchers at Penn State has integrated metasurfaces onto a photonic integrated circuit (PIC) chip. The design maintains high light controllability, allowing guided waves inside the PIC to drive the metasurfaces, enabling routing light among different metasurfaces. The architecture supports the performance of multiple complex functions on a single chip. Led by Xingjie Ni, assistant professor of electrical engineering, the team combined two technologies in its effort to establish more complete light control for use in various optical devices. The approach included taking the...Read full article
