On-demand control of photon echoes far exceeding the spin coherence constraint via coherence swapping between optical and spin transitions
Byoung S. Ham
Using on-demand coherence conversion via optical locking in conventional stimulated (three-pulse) photon echoes, ultralong, ultraefficient photon storage has been observed in a rar…
Active switching in metamaterials using polarization control of light
Hua Xu, Byoung Seung Ham
We demonstrate on-demand control of localized surface plasmons in metamaterials by means of incident light polarization. An asymmetric mode, selectively excited by s-polarized ligh…
Ultralong Efficient Photon Storage Using Optical Locking
Byoung S. Ham
For the last decade quantum memories have been intensively studied for potential applications to quantum information and communications using atomic and ionic ensembles. With the i…
Analysis of Controlled Photon Storage Time Using Phase Locking by Atomic Population Transfer
Byoung S. Ham
Atomic population transfer in an inhomogeneously broadened optical medium is analyzed for on-demand photon storage-time control in both atomic frequency comb (AFC) and phase locked…
Analysis of Optical Deshelving in Photon Echo-based Quantum Memories
Byoung S. Ham
Storage time extension in photon echoes using optical deshelving via a robust spin state has been investigated for absorption-dependent optical leakage, where an incomplete populat…
