Photonic integrated circuits route information with optical signals instead of relying only on electrical currents. Silicon (Si) and silicon nitride (SiNx) are excellent photonic platforms for waveguides, but they cannot ...
Physicists at The City College of New York have demonstrated a new way to transfer microwave signals onto light using magnetic waves inside a layered semiconductor. The work establishes a materials platform for building interfaces ...
