  We have investigated the electronic properties of elliptical quantum dots in
a perpendicular external magnetic field, and in the presence of the Rashba
spin-orbit interaction. Our work indicates that the Fock-Darwin spectra display
strong signature of Rashba spin-orbit coupling even for a low magnetic field,
as the anisotropy of the quantum dot is increased. An explanation of this
pronounced effect with respect to the anisotropy is presented. The strong
spin-orbit coupling effect manifests itself prominently in the corresponding
dipole-allowed optical transitions, and hence is susceptible to direct
experimental observation.
