Abstract

Titanium in-diffused waveguides in lithium niobate is a promising integration platform for building devices for quantum communication, due to its low-loss propagation, high-efficiency coupling to telecom fiber, high second order nonlinearity and electro-optic coefficient. Over recent years we have been investigating the integration of superconducting nanowire single photon detectors (SNSPDs) in this platform, together with the Integrated Quantum Optics group at Paderborn University and colleagues at NIST Boulder. I will report on the proof-of-principle demonstrations of functional devices, as well as discuss our progress to improve the efficiency and yield of on-chip detectors.
