Apparent Microcavity Effect in the Near-Field Photoluminescence of a Single Quantum Dot
Abstract
We present low-temperature near-field scanning optical microscopy (NSOM) measurements of self-organized InP quantum dots (QD) embedded in a 3lamba/2 GaInP layer. We observed an anomalously strong increase of the emission energy (^27O meV) of a single QD by changing the tip-to-surface distance over ^100 nm in the near-field region. The effect indicates formation of a near-field microcavity having extremely high photon-exciton mixing.
