Figure 14From: Submonolayer Quantum Dots for High Speed Surface Emitting LasersPhotoluminescence (PL) and PL excitation spectra of the SML QD structure. The PL spectra are taken at excitation densities of 4 mW/cm2 (solid line) and ∼1 kW/cm2 (dash-dotted line). The PLE spectrum is taken at 1.357 eV, which corresponds to the maximum of the PL intensityBack to article page
