Fabrication of low-loss lithium niobate on insulator waveguides on the wafer scale
Mohammadreza Younesi, Thomas Kasebier, Ilia Elmanov +8
We report on the wafer scale fabrication of single mode low-loss lithium niobate on insulator waveguides utilizing a chemically amplified resist and an optimized dry etching method…
Nonlinear quantum spectroscopy with Parity-Time symmetric integrated circuits
Pawan Kumar, Sina Saravi, Thomas Pertsch +2
We propose a novel quantum nonlinear interferometer design that incorporates a passive PT symmetric coupler sandwiched between two nonlinear sections where signal-idler photon pair…
Group index matched frequency conversion in lithium niobate on insulator waveguides
Pawan Kumar, Mohammadreza Younesi, Sina Saravi +2
Sources of spectrally engineered photonic states are a key resource in several quantum technologies. Of particular importance are the so-called factorizable biphoton states which p…
Mid-Infrared Photon-Pair Generation in AgGaS
Mohit Kumar, Pawan Kumar, Andres Vega +3
We demonstrate non-degenerate photon-pair generation by spontaneous parametric down conversion in a silver gallium sulfide AgGaS crystal. By tuning the pump wavelength, we achi…
Spectral mapping of polarization-correlated photon-pair sources using quantum-classical correspondence
Hung-Pin Chung, Pawan Kumar, Kai Wang +7
Direct spectral characterization of a quantum photon-pair source usually involves cumbersome, costly, and time-consuming detection issues. In this study, we experimentally characte…
