Bright multiplexed source of indistinguishable single photons with tunable GHz-bandwidth at room temperature
Omri Davidson, Ran Finkelstein, Eilon Poem +1
Narrowband single photons that couple well to atomic ensembles could prove essential for future quantum networks, but the efficient generation of such photons remains an outstandin…
Pulsed-pump phosphorus-doped fiber Raman amplifier around 1260 nm for applications in quantum non-linear optics
Eilon Poem, Artem Golenchenko, Omri Davidson +3
We describe a fiber Raman amplifier for nanosecond and sub-nanosecond pulses centered around 1260 nm. The amplification takes place inside a 4.5-m-long polarization-maintaining pho…
Continuous protection of a collective state from inhomogeneous dephasing
Ran Finkelstein, Ohr Lahad, Itsik Cohen +4
We introduce and demonstrate a scheme for eliminating the inhomogeneous dephasing of a collective quantum state. The scheme employs off-resonant fields that continuously dress the…
Power narrowing: Counteracting Doppler broadening in two-color transitions
Ran Finkelstein, Ohr Lahad, Ohad Michel +3
Doppler broadening in thermal ensembles degrades the absorption cross-section and the coherence time of collective excitations. In two photon transitions, it is common to assume th…
Recovering the homogeneous absorption of inhomogeneous media
Ohr Lahad, Ran Finkelstein, Omri Davidson +3
The resonant absorption of light by an ensemble of absorbers decreases when the resonance is inhomogeneously broadened, as only a fraction of the ensemble contributes to the absorp…
