Perfect optomechanically induced transparency in two-cavity optomechanics

Here, we study the controllable optical responses in a two-cavity optomechanical system, especially on the perfect optomechanically induced transparency (OMIT) in the model which has never been studied before. The results show that the perfect OMIT can still occur even with a large mechanical damping rate, and at the perfect transparency window the long-lived slow light can be achieved. In addition, we find that the conversion between the perfect OMIT and optomechanically induced absorption can be easily achieved just by adjusting the driving field strength of the second cavity. We believe that the results can be used to control optical transmission in modern optical networks.

Automated summary

In this study, we investigate controllable optical responses in a previously unstudied two-cavity optomechanical system, focusing on perfect optomechanically induced transparency (OMIT). The findings demonstrate that perfect OMIT can still occur even with high mechanical damping rate, and it enables the achievement of long-lived slow light in the transparent window. Furthermore, we discover that the conversion between perfect OMIT and optomechanically induced absorption can be easily accomplished by adjusting the driving field strength of the second cavity. These results are believed to have implications for controlling optical transmission in modern optical networks.
