Abstract
A whispering gallery mode resonator based on a cylindrical cavity in an optical fiber and a fabrication method thereof are disclosed, which belong to the technical field of optical fiber application. The whispering gallery mode resonator includes an optical fiber body, a cylindrical cavity is provided in the optical fiber body, a top end of the cylindrical cavity is i open, and a bottom end of the cylindrical cavity is located inside the optical fiber body. Part or all of the cylindrical cavity blocks a part of transmitted beam of the optical fiber body, such that the part of the transmitted beam of the optical fiber body is coupled to an inner wall of the cylindrical cavity in a tangential direction, and then periodically propagates on the inner wall of the cylindrical cavity to form a whispering gallery mode.
