H Szymanska — Bose Condensation and Lasing in Optical Microstructures The experimentally obtained Econ for this structure is 54 meV. 4 meV which is still the highest among experimentally obtained structures but much lower than reported by the authors. Our calculation of Econ for five different experimentally realised structures agree very well with the experimental values and thus it is very probable that the value of 54 meV is overestimated. 6 meV for this structure. We can conclude from our results that the optimised asymmetric structure does not lead to a bigger exciton binding energy than the symmetric ones with the same parameters.

Because our system is finite we obtain only a sampling of the continuum states. When we increase the unit cell size we automatically calculate more states within the same energy region and they do not have a one to one correspondence with the states calculated using a smaller unit cell. The new states appear in between the old ones, with smaller oscillator strengths so that the total oscillator strength is conserved. 2). 5 are converged in the sense that the continuum is accurately sampled on the scale of 4meV.
