This project aims to couple a multimode optical fiber(MMF) to a superconducting nanowire single-photon detector(SNSPD) and characterize it. SNSPDs are currently the most sensitive single-photon detectors available. But most of the current SNSPDs are coupled using single-mode fibers(SMF), which collect photons in only one spatial mode. This is inefficient when collecting photons from biological samples, […]
