We report on the experimental demonstration of an optical spin-wave memory, based on the
atomic frequency comb (AFC) scheme, where the storage efficiency is strongly enhanced by …

We demonstrate efficient storage and retrieval of light pulses by electromagnetically induced
transparency (EIT) in a Pr 3+: Y 2 SiO 5 crystal. Using a ring-type multipass configuration, we …

Optical microcavities with ultralong photon storage times are of central importance for
integrated nanophotonics. To date, record quality (Q) factors up to 10 11 have been …

We report on the high-efficiency storage and retrieval of weak coherent optical pulses and
photonic qubits in a cavity-enhanced solid-state quantum memory. By using an atomic …

We seek to design experimentally feasible broadband, temporally multiplexed optical
quantum memory with near-term applications to telecom bands. Specifically, we devise …

On-chip optical filters are fundamental components in optical signal processing. While rare-
earth ion-doped crystals offer ultra-narrow optical filtering via spectral hole burning, their …

Ensembles of dopants have widespread applications in quantum technology. The
miniaturization of corresponding devices is however hampered by dipolar interactions that …

Coherent nonlinear multipulse processes, nonlinear waves, and echo effects in resonant
media are the topical problems of modern optics and important tools of coherent …

We compare the Autler–Townes (AT)-splitting in \rmEu^3+:\rmYPO_4 Eu^ 3+: YPO_4,
\rmPr^3+:\rmYPO_4 Pr^ 3+: YPO_4, and \rmPr^3+:\rmY_2\rmSiO_5 Pr^ 3+: Y_2SiO_5 …

We have demonstrated a laser in which the frequency shift due to small cavity fluctuations is
far less than what would be expected from a conventional laser. The factor of sensitivity …
