Abstract
Abstract
In this paper, we demonstrate a simple scheme to achieve Fano-like and electromagnetically induced transparency (EIT) like resonance by changing the coupling position of a high-Q spherical microbubble cavity with tapered fiber. The evolution processes of the Fano-like and EIT-like spectrums are explored from simulation and experiment, which are in good agreement. And a high sensitivity pressure sensor based on Fano-like resonance is realized. It shows that compared with the slopes of the Lorentz lineshape, Fano-like and EIT-like lineshapes are increased by 2.7 and 20.7 times, respectively. It provides a simple method for ultra-high sensitive sensing.
