This research investigates the influence of rotation on the propagation of optical acoustic waves caused by the motion of an optical carrier in an elastic thermal environment. The study employs theoretical analysis to derive governing equations tailored to a nonlocal semiconductor medium, incorporating the interaction between acoustic waves and thermomechanics. The foundational equations of the model, influenced by photothermal and thermoelastic principles, are mathematically derived when the microstructure of the medium is taken into consideration while accounting for rotation. The model explores the medium's response to a thermal ramp originating from light-induced temperature elevation. The mathematical model is solvable in two-dimensional (2D) using the normal mode method, and numerical solutions offer insights into various physical fields, such as displacements, temperature, acoustic pressure, mechanical distributions, and carrier density diffusion. Employing the harmonic wave method, some graphical representations of the rotation parameter are obtained, both with and without the influence of the nonlocal parameter. Theoretical analysis includes a comprehensive examination, comparison, and discussion of the effects of these parameters on the system subjected to ramp-type heating.
