Paper Abstract

Metallic metamaterial structures are used in nanophotonics applications in order to localize and enhance an incident electromagnetic field. We have theoretically and experimentally studied resonant coupling between plasmonic modes of an SRR array and a quantum dot-in-a-well (DWELL) heterostructure. The near-field distribution from the SRRs on the GaAs substrate was first modeled by electromagnetic simulations and optimized SRR dimensions for maximum nearfield coupling at the peak absorption were extracted. The DWELL sample with a ground state emission peak at 1240 nm was grown by molecular beam epitaxy on a semi-insulating GaAs substrate. The sample was uniformly covered with an array of SRRs, and patterned by standard electron-beam-lithography. In order to study the near field coupling of the plasmonic structure into the DWELL, optical characterization was performed on the SRR-DWELL heterostructure, including room temperature photoluminescence, and transmission measurement.
