A Comparison of Integrated Photonic Platforms for Broadband Entangled-Pair Generation (JW5A.59)

Presenter: Liao Duan, UCSB

We report nonlinear integrated photonic microresonator designs enabling > 1 THz/mW2 broadband pair generation rates. Simulations show a novel cross-polarized type- 1 four-wave mixing phase-matching technique to further extend the bandwidth deeper into the visible spectrum.

AlGaAs Microring Resonator Array for Dense Spectral Multiplexing and Multi-Mode Entangled-Pair Generation (LW6F.2)

Presenter: Yiming Pang, UCSB

We report an AlGaAs microresonator array enabling dense multiplexing of high-rate 1550 nm entangled-pair sources. Quantum combs are offset by 12.5 GHz and pumped with an electro-optic comb producing up to 4 GHz/mW^2 pair rate per resonator.
