Phase Control of Spontaneous Emission
The control of spontaneous emission has attracted much attention for many years. For atoms in free space, atomic coherence and quantum interference are the basic phenomena for controlling spontaneous emission [1– 3]; these have potential applications to lasing without inversion [4–10]. Zhu, Scully, and co-workers have studied the quenching of spontaneous emission using an open V-type atom [11],...
متن کاملPhase-space analysis of bosonic spontaneous emission
We present phase-space techniques for the modelling of spontaneous emission in two-level bosonic atoms. The positive-P representation is shown to give a full and complete description within the limits of our model. The Wigner representation, even when truncated at second order, is shown to need a doubling of the phase-space to allow for a positive-definite diffusion matrix in the appropriate Fo...
متن کاملControl of spontaneous emission in photonic crystals
We studied enhancement and suppression of spontaneous emission in thin-film InGaAs/InP photonic crystal at room temperature. Angular resolved photoluminescence measurements were used to determine experimentally the band structure of conduction band of such a photonic crystal and overall enhancement of spontaneous emission. We demonstrated spontaneous emission enhancement in thin slab photonic c...
متن کاملUltrafast non-local control of spontaneous emission.
The radiative interaction of solid-state emitters with cavity fields is the basis of semiconductor microcavity lasers and cavity quantum electrodynamics (CQED) systems. Its control in real time would open new avenues for the generation of non-classical light states, the control of entanglement and the modulation of lasers. However, unlike atomic CQED or circuit quantum electrodynamics, the real...
متن کاملCharacteristics of Dual Amplified Spontaneous Emission from MEH-PPV Solutions
We report the observations of dual wavelength amplified spontaneous emission from the solutions of a conjugated polymer poly [2-methoxy-5-(2-ethylhexyloxy)-1, 4-phenylenevinylene] (MEH-PPV) in Tetrahydrofuran and 1, 2 Dichlorobenzene. We have prepared MEH-PPV using a modified procedure and purified several times in each step, the material offers low molecular weight, low polydispersity index an...
