(a) Schematic view of the electrically pumped micropillar laser structure. (b) Scanning electron microscope image of a diameter micropillar laser after planarization with BCB. A small gap evolves between the upper part of the micropillar and the BCB which is filled by Au during the metallization of the -contact ensuring lateral current injection through the pillar sidewall.
(a) spectra of a micropillar laser below [ (inset), ] and above laser threshold at . Current induced heating leads to a redshift of the fundamental mode emission. (b) Input-output characteristic of the microlaser with a threshold current of . Inset: emission mode linewidth (FWHM) vs injection current.
(a) Input-output characteristics of micropillar lasers with different diameters in log-log scale and linear scale (inset). Solide lines: fit curves according to a rate equations model. (b) Second order photon autocorrelation function vs injection current for a micropillar. (c) Threshold current of a micropillar laser as a function of temperature.
