In this paper, we investigate theoretically the effects of a spatially varying effective mass distribution on the electronic and optical properties of octic anharmonic oscillators. Calculations to determine eigenvalues and eigenfunctions of the electron are performed within the effective mass approximation by using the diagonalization method. Optical absorption coefficients are obtained from the two-level approach in the density matrix expansion. Numerical results show that the position-dependent effective mass has a significant effect on the electronic energies and transitions between the subbands in single and double octic anharmonic oscillators. Furthermore, it was found that the optical properties of the system can be tailored in accordance with the desired purpose by changing the structural parameters of the system determining the size and the shape and with a proper choice of effective mass distribution.
