Abstract
We study the ground and the first excited states’ energies and the corresponding transition frequency of a strongcoupling polaron in an asymmetric quantum dot AQD The effects of the electric field the transverse and the longitudinal effective confinement lengths and the electronphonon coupling strength are taken into account by using a variational method of the Pekar type It is found that the ground and the first excited states’ energies and the transition frequency are decreasing functions of the electric field They will increase rapidly with decreasing the transverse and longitudinal effective confinement lengths The transition frequency is an increasing function of the electronphonon coupling strength whereas the energies are decreasing ones of it
