Calculated oscillator strengths for crossed linear optical polarizations along the directions [ 0 1 ¯ 1 ] ( red line ) and [011] ( blue line ) for two coupled QD's (Figure 1c) with semicylindrical shape and axis in the [ 0 1 ¯ 1 ] direction with (a) D [ 0 1 ¯ 1 ] = 280 Å, d = 160 Å upon strain order of ε || = - 0.3% ( solid line ) and -0.9% ( dashed line ). (b) D [ 0 1 ¯ 1 ] = 350 Å, d = 330 Å and ε || = - 0.1% ( solid line ), -0.2% ( dashed line ) and -0.3% ( dashed-dotted line ). The crossing point stands for isotropic optical emission.
