Light Confinement in Coherently Driven Defect States in Solids

Inhomogeneously broadened optical transitions in nitrogen-vacancy color centers in diamond and Pr(3+) doped yttrium orthosilicate may he employed to attain all-optically controlled Bragg structures with photonic band-gaps of high reflectivities and large bandwidths. Such a control mechanism is valuable for improving performance and scalability of solid quantum memory devices.
