We investigate the scattering of single photons by single atoms and, in particular, the dependence of the atomic dynamics and the scattering probability on the photon bandwidth. We tightly focus the incident photons onto a single trapped 87Rb atom and use the time-resolved transmission to characterize the interaction strength. Decreasing the bandwidth of the single photons from 6 to 2 times the atomic linewidth, we observe an increase in atomic peak excitation and photon scattering probability.

Using an injection-locked VCSEL to produce Fourier-transform-limited optical pulses.
Fourier-transform-limited, nanosecond scale optical pulses from a vertical cavity surface emitting laser (VCSEL) using injection locking with a narrow-band seed laser indicates that injection-locked VCSELs could become a key component of large-scale photonic quantum networks. Expand

Generation of sub-MHz and spectrally-bright biphotons from hot atomic vapors with a phase mismatch-free scheme.
The all-copropagating scheme, which maintains the phase-match condition, is utilized in the spontaneous four-wave mixing (SFWM) process to generate biphotons from a hot atomic vapor, which has the narrowest linewidth to date among all single-mode biphoton sources of room-temperature and hot media.

Spectral Compression of Narrowband Single Photons with a Resonant Cavity.
A spectral compression scheme for heralded single photons with narrow spectral bandwidth around 795 nm, generated through four-wave mixing in a cloud of cold ^{87}Rb atoms, and can be, in principle, without any optical losses. Expand

Time-resolved scattering of a single photon by a single atom
The scattering of heralded photons from a single trapped atom is experimentally investigated and it is demonstrated that the atomic dynamics depend on whether the temporal envelope of the photon wave packet is exponentially decaying or rising. Expand

Light-matter interaction in free space
Free space cavity QED comprises the interaction with a continuum of modes and does not allow for observing oscillatory exchange between the light field and the atom which is the characteristic feature of strong coupling in cavityQED. Expand
