Integrated Optics for Single-Photon Nonlinear Interactions
Abstract
Integrated Optics for Single-Photon Nonlinear InteractionsWe propose to investigate how to realize and leverage ultra-strong nonlinear interactions forapplications in quantum photonics. We plan to exploit a recently developed processing methodwhere waveguides are created by rib-loading thin-film lithium niobate (LN). The technique canproduce submicron mode sizes that are one the order of" two orders of magnitude smaller than theincumbent technologies such as reverse proton exchange waveguides, thereby leading to grea"tlyenhanced effective nonlinearity and much higher component density. Stronger nonlinearities willbolster functions like entanglement swapping via nonlinear-assisted bell state measurements byimproving the effective rate at which these normally inefficient processes operate by orders ofmagnitude. This function can be used to create a heralded entangled photon source which is acritical and yet unmet tool for quantum information processing. Other functions like low lossswitches are also easily integrated into the rib-loaded LN platform allowing for more efficientmanipulation and combination of temporal modes. This again leads to much higher effici"encyand substantial rate improvements over state-of-the-art quantum photonic processors. Moreover,the devices are integrated on a" silicon substrate and are compatible with large-scale photonicintegration.
