Stevenson, R M and Young, R J and See, P and Norman, C E and Shields, A J and Atkinson, P and Ritchie, D A (2005) Strong directional dependence of single-quantum-dot fine structure. Applied Physics Letters, 87 (13). -. ISSN 0003-6951Full text not available from this repository.
By isolating quantum dots in microstructures with cleaved facets, we measure individual-quantum-dot photoluminescence emitted in the in-plane direction, in addition to the widely studied vertical direction. The emission is shown to be polarized in the plane, and the observed fine structure is found to be extremely directionally-dependent. These characteristics are attributed to exciton states with orthogonally aligned dipoles in the plane. The result suggests possibilities for single-quantum-dot devices, including side-emitting single-photon sources. (C) 2005 American Institute of Physics.
