| contents | This study explores the linear and nonlinear optical absorption coefficients (OAC) and refractive index changes (RIC) in quantum dot and quantum antidot systems with a position-dependent variable effective mass. Significant contributions to both linear and nonlinear OAC and RIC are observed. Our findings reveal that variations of the mass parameter modify the intersubband dipole matrix elements and energy intervals, leading to noticeable shifts in optical properties. The results show that higher γ values shift resonance peaks towards higher energies, while changes in the oscillator frequency result in abrupt shifts and peak diminutions. These insights provide a deeper understanding of the optical behaviors in the quantum systems under consideration, paving the way for designing devices with optimal efficiency |
