- Abstract: Nonclassical phenomena can be enhanced by introducing $q$-deformation in
optomechanical systems. This motivates investigation of the optical response in
a $q$-deformed linearly coupled optomechanical system. The system consists of
two deformed cavities that are linearly coupled to the motion of mechanical
mirrors, and the cavities are coupled to each other by transmission strength
parameter. This study shows that compared to non-deformed cases, the deformed
system exhibits more rapid phase transition at the positions of transparency
windows, causing stronger and enhanced fast and slow light phenomena. Moreover,
in the region $0<q<0.5$, the optomechanical system results in gain.
Additionally, for a fixed deformation of cavities, by tuning the tunneling
strength and optomechanical coupling, one can observe a delay and advancement
in probe field in the order of milliseconds and even above milliseconds for
fine-tuning of the coupling parameters. Finally, the bridge between
mathematical and physical models is built by assuming the deformation to be a
primitive root of unity, which indicates a class of anyon models. These results
demonstrate that $q$-deformation provides a novel method for manipulating and
significantly enhancing optical phenomena not only in arbitrarily deformed
optomechanical systems but also in anyon models.
