Parallel piezo aligners with fly height sensors enable faster PIC wafer testing.
Abstract: This study investigates alignment and coupling between a photonic integrated circuit (PIC) and a mixed-mode fiber array (FA), where one of the channels in the normally single-mode (SM) array ...
Abstract: While fiber-optic quantum key distribution (QKD) systems have reached a technological maturity that permits field deployments, the complexity of free-space optical (FSO) QKD systems ...
