Pronounced Purcell enhancement of spontaneous emission in CdTe/ZnTe quantum dots embedded in micropillar cavities

Broadband Purcell enhancement in plasmonic ring cavities

We present a theoretical study of a surface plasmon ring resonator geometry that shows strong spontaneous emission control due to an extremely small optical cavity mode volume. V grooves made in the surface of a metal confine whispering gallery surface plasmon polariton modes at the bottom of the groove, with the confinement determined by groove depth and width. Resonances in ringlike cavities ...

Modified spontaneous emission properties of CdS quantum dots embedded in novel three-dimensional microcavities

Modified spontaneous emission properties in the presence of confined photon modes inside the three-dimensional (3-D.) optical microcavities are demonstrated. Self-formed pyramidal-shaped semiconductor structures fabricated by selective-area growth technique are utilized as an optical microcavity in which discrete photon modes are generated. Noticeable modification of spontaneous emission from a...

Spontaneous emission enhancement of quantum dots in a photonic crystal wire.

Photonic wires are the simplest extended low-dimensional systems. Photonic crystal confinement confers them a divergent density of states at zero-group-velocity points, which leads to enhancement of spontaneous emission rates [D. Kleppner, Phys. Rev. Lett. 47, 233 (1981)10.1103/Phys. Rev. Lett. 47.233]. We experimentally evidence, for the first time, the spectral signature of these Purcell fact...

Fiber-Coupled Microdisk Cavities with Embedded Quantum Dots

High-Q photonic crystal cavities with embedded quantum dots

Defects in photonic crystals (PCs) can support localized light modes with extremely small mode volumes. Depending on the symmetry of the PC, and the means of fabrication of the PC, extremely high quality factors (Q) are also possible. The combination of high Q and small mode volume should allow us to observe strong coupling between the cavity and quantum dot (QD) emitters that are strategically...
