Ultralong Photon Echo Storage Using Optical Locking
B. S. Ham, J. Hahn
An ultralong photon storage with more than 50% retrieval efficiency is presented in the three-pulse photon echoes by using a pair of control pulses, where the control pulses play t…
Phase Locked Photon Echoes for Extended Storage Time
B. S. Ham
We report a quantum optical storage time-extended near perfect photon echo protocol using a phase locking method via an auxiliary spin state, where the phase locking acts as a cond…
Slow light enhanced photon echoes
J. Hahn, B. S. Ham
We report a slow light-enhanced photon echo method, whose retrieval efficiency is two orders of magnitude higher than that of conventional photon echoes. The enhanced photon echo e…
Towards Bose-Einstein condensation of excitons in an asymmetric multi-quantum state magnetic lattice
A. Abdelrahman, M. Vasiliev, K. Alameh +3
An asymmetric multi-quantum state magnetic lattice is proposed to host excitons formed in a quantum degenerate gas of ultracold fermionic atoms to simulate Bose-Einstein condensati…
Plasmon-induced photonic switching in a metamaterial
H. Xu, B. S. Ham
Using light-induced localized surface plasmon interactions in a metamaterial, we present a plasmonic control of light absorption for photonic switching. We discuss that the present…
Ultralong trapping of light using double spin coherence gratings
B. S. Ham, J. Hahn
Ultralong trapping of light has been observed in an optically dense three-level solid medium interacting with a pair of counterpropagating coupling fields. Unlike the light trappin…
