Wereport on the magnetic field dispersion of the exciton spin-splittingand diamagnetic shift in single InAs/GaAs quantum dots up toB=28 T. We have found substantial differences between field evolution ofthe emission from tall (4 nm height) and flat (2 nm height)dots. Strongly nonlinear spin-splitting is observed in the former case,while in the latter case the nonlinearity is much weaker.The diamagnetic shift of the ground-state emission can be explainedin terms of geometric size of the dots. While itcan be approximated by a quadratic field dependence in dotsof large confining potential, a substantial linear contribution must beincluded to account for the diamagnetic shift in dots ofweaker confinement.
