Abstract
A whispering gallery mode resonator and a manufacturing method includes a hollow core fiber, a waveguide, a waveguide resonant cavity, a first single-mode fiber and a second single-mode fiber. The waveguide and the waveguide resonant cavity are located in the hollow core fiber. End surface of the first and second single-mode fibers are fused to end surfaces of the hollow core fiber. The waveguide includes an input optical waveguide, an inner surface waveguide having an evanescent field and an output optical waveguide. The two end surfaces of the input optical waveguide are connected with an end surface of the core of the first single-mode fiber and an end surface of the inner surface waveguide respectively. The two end surfaces of the output optical waveguide are connected with an end surface of the core of the second single-mode fiber and the other end surface of the inner surface waveguide respectively.
