Temporally-ultralong biphotons with a linewidth of 50 kHz
Yu-Sheng Wang, Kai-Bo Li, Chao-Feng Chang +9
We report the generation of biphotons, with a temporal full width at the half maximum (FWHM) of 13.40.3 s and a spectral FWHM of 501 kHz, via the process of spontaneou…
Temporal profile of biphotons generated from a hot atomic vapor and spectrum of electromagnetically induced transparency
Shih-Si Hsiao, Wei-Kai Huang, Yi-Min Lin +3
We systematically studied the temporal profile of biphotons, i.e., pairs of time-correlated single photons, generated from a hot atomic vapor via the spontaneous four-wave mixing p…
Increasing decoherence rate of Rydberg polaritons due to accumulating dark Rydberg atoms
Ko-Tang Chen, Bongjune Kim, Chia-Chen Su +4
We experimentally observed an accumulative type of nonlinear attenuation and distortion of slow light, i.e., Rydberg polaritons, with the Rydberg state in the w…
Room-temperature biphoton source with a spectral brightness near the ultimate limit
Jia-Mou Chen, Chia-Yu Hsu, Wei-Kai Huang +7
The biphotons, generated from a hot atomic vapor via the process of spontaneous four-wave mixing (SFWM), have the following merits: stable and tunable frequencies as well as linewi…
Generation of sub-MHz and spectrally-bright biphotons from hot atomic vapors with a phase mismatch-free scheme
Chia-Yu Hsu, Yu-Sheng Wang, Jia-Mou Chen +11
We utilized the all-copropagating scheme, which maintains the phase-match condition, in the spontaneous four-wave mixing (SFWM) process to generate biphotons from a hot atomic vapo…
A Weakly-Interacting Many-Body System of Rydberg Polaritons Based on Electromagnetically Induced Transparency
Bongjune Kim, Ko-Tang Chen, Shih-Si Hsiao +9
We proposed utilizing a medium with a high optical depth (OD) and a Rydberg state of low principal quantum number, , to create a weakly-interacting many-body system of Rydberg p…
Mean field theory of weakly-interacting Rydberg polaritons in the EIT system based on the nearest-neighbor distribution
Shih-Si Hsiao, Ko-Tang Chen, Ite A. Yu
The combination of high optical nonlinearity in the electromagnetically induced transparency (EIT) effect and strong electric dipole-dipole interaction (DDI) among the Rydberg-stat…
Effect of laser frequency fluctuation on the decay rate of Rydberg coherence
Bongjune Kim, Ko-Tang Chen, Chia-Yu Hsu +8
The effect of electromagnetically induced transparency (EIT) combined with Rydberg-state atoms provides high optical nonlinearity to efficiently mediate the photon-photon interacti…
