Multimode regimes in quantum cascade lasers: From coherent instabilities to spatial hole burning RID B-8648-2009
(American Physical Society, 2008)
A theoretical and experimental study of multimode operation regimes in quantum cascade lasers (QCLs) is presented. It is shown that the fast gain recovery of QCLs promotes two multimode regimes: One is spatial hole burning ...
Three-qubit phase gate based on cavity quantum electrodynamics
(American Physical Society, 2008)
We describe a three-qubit quantum phase gate which is implemented by passing a four-level atom in a cascade configuration initially in its ground state through a three-mode optical cavity. The three qubits are represented ...
Control of the Goos-Hanchen shift of a light beam via a coherent driving field RID A-4660-2010
(American Physical Society, 2008)
We present a proposal to manipulate the Goos-Hanchen shift of a light beam via a coherent control field, which is injected into a cavity configuration containing the two-level atomic medium. It is found that the lateral ...
