Reversible quantum optical data storage based on resonant Raman optical field excited spin coherence
B. S. Ham
A method of reversible quantum optical data storage is presented using resonant Raman field excited spin coherence, where the spin coherence is stored in an inhomogeneously broaden…
Quantum coherent control of self-induced ultraslow light
B. S. Ham, J. S. Han
Quantum coherent control of slow light for all-optical switching is investigated in a multi-level system of solids for an understanding of self-induced ultraslow light. In an optic…
Ultralong quantum optical storage using reversible inhomogeneous spin ensembles with an optical locking method
Byoung S. Ham
A novel method of multi-bit quantum optical data storage is presented, where the storage time can be lengthened far beyond the spin phase-decay time in a reversible spin inhomogene…
Observations of time delayed all-optical routing in a slow light regime
B. S. Ham
We report an observation of a delayed all-optical routing/switching phenomenon based on ultraslow group velocity of light via nondegenerate four-wave mixing processes in a defected…
