	abstract = {  We study the modification of a traditional electromagnetically induced
transparency (EIT) stored light technique that includes both EIT and four-wave
mixing (FWM) in an ensemble of hot Rb atoms. The standard treatment of light
storage involves the coherent and reversible mapping of one photonic mode onto
a collective spin coherence. It has been shown that unwanted, competing
processes such as four-wave mixing are enhanced by EIT and can significantly
modify the signal optical pulse propagation. We present theoretical and
experimental evidence to indicate that while a Stokes field is indeed detected
upon retrieval of the signal field, any information originally encoded in a
seeded Stokes field is not independently preserved during the storage process.
We present a simple model that describes the propagation dynamics of the fields
and the impact of FWM on the spin wave.

	abstract = {  We study procedures for the optimization of efficiency of light storage and
retrieval based on the dynamic form of electromagnetically induced transparency
(EIT) in warm Rb vapor. We present a detailed analysis of two recently
demonstrated optimization protocols: a time-reversal-based iteration procedure,
which finds the optimal input signal pulse shape for any given control field,
and a procedure based on the calculation of an optimal control field for any
given signal pulse shape. We verify that the two procedures are consistent with
each other, and that they both independently achieve the maximum memory
efficiency for any given optical depth. We observe good agreement with
theoretical predictions for moderate optical depths (<25), while at higher
optical depths the experimental efficiency falls below the theoretically
predicted values. We identify possible effects responsible for this reduction
in memory efficiency.

	abstract = {  We experimentally demonstrate optimal storage and retrieval of light pulses
of arbitrary shape in atomic ensembles. By shaping auxiliary control pulses, we
attain efficiencies approaching the fundamental limit and achieve precise
retrieval into any predetermined temporal profile. Our techniques, demonstrated
in warm Rb vapor, are applicable to a wide range of systems and protocols. As
an example, we present their potential application to the creation of optical
time-bin qubits and to controlled partial retrieval.
