Abstract:
We report on single-mode stimulated emission at a wavelength of 510nm in monolithic high-Q ZnSe-based vertical-cavity surface-emitting laser (VCSEL) micropillars under optical excitation at 280K. Calculations reveal the influence of polariton coupling and the dynamic detuning of the gain maximum to the cavity modes on the spectral characteristics of the VCSEL emission. In accordance with theory, we find a systematic decrease in threshold excitation energy for decreasing pillar diameter to a minimum value of 0.09pJ for a pillar diameter of 1.2μm as a combined effect of reduced active area and reduced mode volume in the microcavity lasers.
