Frequency conversion in nonlinear waveguides for noise resilient quantum inspired LiDAR
Amr S Helmy
University of Toronto, Canada
Optical correlations are useful for many sensing and metrology applications including imaging, interferometry and LiDAR. Quantum illumination (QI) is a special example: it uses non-classical optical correlation (entanglement) to effectively filter uncorrelated noise from real LiDAR signals. Despite its impact QI only excels in the few photon regime. Therefore, when built using inherently low power quantum sources QI cannot compete with classical LiDAR systems with mW level probe light. In this talk we demonstrate quantum-inspired LiDAR which utilizes broadband phase correlations in nonlinear waveguides with effective second order nonlinearities, to effectively reduce in-band noise power by over 100dB with single-photon sensitivity. It is empowered by a receiver which utilizes sum-frequency in optical waveguides with record conversion efficiency.
