An on-centre hydrogenic impurity in a GaAs/AlGaAs quantum disk with azimuthal distortion has been considered. The complete energy spectrum as well as the transition matrix elements have been worked out numerically. The linear and non-linear susceptibilities, absorption coefficients and changes in refractive index have been calculated for various configurations of the system. The non-central nature of the potential has been found to alter these optical properties to a great extent. The application of external magnetic and static electric fields as well as disk size have been found to have considerable influence on these properties of the distorted quantum disk. It is believed that the present results would be beneficial in designing of optoelectronic devices.
