Quantum Optical Sources in Photonic Band Structures.
Abstract
The advent of 3D periodic dielectric structure possessing photonic band gaps (PBGs) and the ability to incorporate defects in the structure, offer far greater control over the spatial modulation of the field amplitude, and the spectral distribution of its mode density. Novel quantum optical processes which rely on the design of the field characteristics in PBG structures: (1) Quantum states via nonadiabatic periodic transitions: Unusual nonadiabatic dynamics of field dressed atomic states obtained for atoms moving along a near resonant periodically modulated field mode. Such dynamics, permits an extremely powerful control over the photon number and phase distributions of the field. (2) Pump mode Fock state generation: Atomic states dressed by the defect field can decay via coupling to the mode continuum into a state, which upon measurement of the atomic state, corresponds to a single Fock state of the field. (3) Lasing without inversion. Spontaneous decay of an atom whose resonance is located between two PBGs is found to produce coherence between adjacent atomic sublevels. This can be used to generate electromagnetically induced transparency, lasing without inversion and nonclassical light.
