- Authors: Xiao-Bo Yan
- Abstract summary: We theoretically study how to achieve the ultraslow and ultrafast light in a passive-active optomechanical system.
The ultraslow light can be easily achieved at the transparency window by adjusting the dissipation rates of the two cavities.
The ultrafast light can be achieved at transparency window by tuning the coupling strength and the decay rates in the system.

- Abstract: Slow and fast light is an important and fascinating phenomenon in quantum
optics. Here, we theoretically study how to achieve the ultraslow and ultrafast
light in a passive-active optomechanical system, based on the ideal
optomechanically induced transparency (OMIT). Under the conditions of the ideal
OMIT, an abnormal (inverted) transparency window will emerge accompanied with a
very steep dispersion, resulting that the ultraslow light can be easily
achieved at the transparency window by adjusting the dissipation rates of the
two cavities, even with usual mechanical linewidth (such as Hz linewidth).
Particularly, as the decay rate of the passive cavity tends to the gain rate of
the active cavity, the ideal stopped light can be achieved. Similarly, the
ultrafast light can be achieved at transparency window by tuning the coupling
strength and the decay rates in the system.
