The structural non-uniformity of the fabricated Quantum Disks is modelled in terms of a non-central potential having azimuthal distortion. The time independent Schrödinger equation for an on-centre hydrogenic impurity in a circular Quantum Disk is solved by employing a combination of Bessel Basis Set method and the Finite Difference method. The resultant energy spectrum and wave functions are used to determine the linear and non-linear optical properties using the compact-density matrix approach. The focus is on the role of azimuthal distortion in modifying the effect of hydrostatic pressure and temperature on the optical properties. The study is performed both in the presence and absence of external magnetic field. The result of varying various control parameters, viz., pressure, temperature, magnetic field and strength of distortion, is studied in the form of shift in the photon frequency corresponding to maxima of observed properties as well as change in their magnitudes. The observations predict appreciable dependence of the optical properties on these parameters.
