Fig. 1b : Simulated normalised far-field intensity,angular emission profile above a 2.00 µm diameter micropillar with 7 (26) upper (lower) DBR pairs. ASCII file in table format.<br>Fig. 1c,d : Simulated emission power spectrum in the upward direction and summed over all directions. ASCII file with 3 columns for [Wavelength, Upward emission, All emission].<br>Fig. 1ef: Purcell factor, cavity mode emission, and non-cavity mode emission and spontaneous emission (SE) coupling factor as a function of pillar diameter. ASCII file of columns with [Diameter, Purcell Factor, G_c, G_l, Beta].<br>Fig. 2a/b/c/d : Purcell factor for a source in the centre of the spacer layer, in a Bragg cavity (a,b) or uniform (c,d) pillar as a function of pillar diameter. In (a,c) only the emission through the top and bottom monitors T_(+z) and T_(-z) are considered while in (b,d) emission through all sides is considered. ASCII files in table format with wavelength along first column and diameter in first row.<br>Fig. 3a/b/c/d : Purcell factor for a source in a Bragg cavity (a,b) or uniform (c,d) pillar for a constant pillar diameter of 1.85 µm , as function of the source height. In (a,c) only the emission through the top and bottom monitors T_(+z) and T_(-z) are considered while in (b,d) emission through all sides is considered. ASCII files in table format with wavelength along first column and source height in first row.<br>Fig. 4a/b/c/d : Purcell factor for a source in the centre of the spacer layer, in a Bragg cavity (a,b) or uniform (c,d) pillar for a constant pillar diameter of 1.85 µm , as function of an additional GaAs layer added to the top of the pillar. In (a,c) only the emission through the top and bottom monitors T_(+z) and T_(-z) are considered while in (b,d) emission through all sides is considered. ASCII files in table format with wavelength along first column and GaAs thickness in first row.<br>Fig. 5a/b/c/d/e/f : Absolute electric field |E| cross-sectional profiles for 1.85 µm micropillars (grey outline) at the HE11 mode wavelength for a cavity pillar excited by a dipole at the cavity mode anti-node (z = 0 µm) in the centre of the spacer layer, in (a) on the y = 0 plane (x-z), parallel to the dipole and in (b) on the x = 0 plane (y-z), perpendicular to it. (c, d) as (a, b), but for a dipole at the lower cavity mode node (z = -0.067 µm). (e,f) as (a, b), but for a uniform micropillar. ASCII files in table format with x-coordinate along first column and y-coordinate in first row.
