Design of a high-Q fiber cavity for omnidirectionally emitting laser with one-dimensional topological photonic crystal heterostructure

This is the authors' abstract. We don't add key points for this paper.

. Moreover, a method of further improving the Q-factor is proposed. The results in this paper are not restricted to the solid gain medium, and they also can be applied to designing a cavity for optofluidic OEL or quantum dot OEL. Our study may provide not only the reference for OEL manufacture, but also a route for improving the performance of OEL.
