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…
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…
Super-extended nanofiber-guided field for coherent interaction with hot atoms
Ran Finkelstein, Gal Winer, David Zeev Koplovich +8
We fabricate an extremely thin optical fiber that supports a super-extended mode with a diameter as large as 13 times the optical wavelength, residing almost entirely outside the f…
Signatures of the -mode anomaly in (1+1) dimensional periodically-driven topological/normal insulator heterostructures
Yiming Pan, Zhaopin Chen, Bing Wang +1
Akin to zero-mode anomalies, such as the chiral anomaly of edge states in quantum Hall effect, in this work, a pi-mode anomaly is proposed in a 1+1 dimensional periodically-driven…
Quantum vortices of strongly interacting photons
Lee Drori, Bankim Chandra Das, Tomer Danino Zohar +4
Vortices are a hallmark of topologically nontrivial dynamics in nonlinear physics and arise in a huge variety of systems, from space and atmosphere to condensed matter and quantum…
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…
