Correlated photon-pair generation in a liquid-filled microcavity
We report on the realization of a liquid-filled optical microcavity and demonstrate photon-pair generation by spontaneous four-wave mixing. Our source has a spectral brightness of 45 ± 7 mW ^−2 s ^−1 MHz ^−1 and the bandwidth of the emitted photons is ∼300 MHz. We demonstrate tuning of the emission...

| description | We report on the realization of a liquid-filled optical microcavity and demonstrate photon-pair generation by spontaneous four-wave mixing. Our source has a spectral brightness of 45 ± 7 mW ^−2 s ^−1 MHz ^−1 and the bandwidth of the emitted photons is ∼300 MHz. We demonstrate tuning of the emission wavelength between 770 and 800 nm. Moreover, by employing a liquid as the nonlinear optical medium completely filling the microcavity, we observe more than a factor 10 ^3 increase of the pair correlation rate per unit pump power and a factor of 1.7 improvement in the coincidence/accidental ratio as compared to our previous measurements. |
