Photonic Molecule Formation in Microsphere Ensembles Doped With Quantum Dots — •Björn M. Möller1, Mikhail V. Artemyev1, Reinhold Wannemacher2, and Ulrike Woggon1 — 1Universität Dortmund — 2Universität Leipzig
Semiconductor nanocrystals in spherical microcavities represent a promising material system for the development of thresholdless lasers and studies of light-matter-interaction regimes [1].
In this work, we report on the experimental observation of coherent cavity field coupling in ensembles of spherical poystyrene microcavities doped with CdSe quantum dots. The spatial dependence and polarization nature of both the unperturbed cavity fields and the coupled binding resonances are studied spectrally resolved in various one- and two-dimensional multisphere geometries. A mode mapping analysis [2] clearly reveals the symmetry properties of the agglomerates for both types of resonances and offers a detailed view of the optical confinement in sphere based photonic molecules impregnated with nanoemitters.
