The fabrication of a tapered fiber connector and its coupling efficiency

Abstract

In order to reduce the adverse influence of transversal displacement of the optical fiber connector, we propose the directional tapered communication fiber connector, in which the fiber head is tapered according to the signal transmission direction to improve efficiency. We used a flame-brush technique to produce the tapered fiber successfully. In the next step, two experiments in different environments were performed; one in a static environment and the other in a vibration environment. The first experiment shows that the efficiency of the tapered connector is higher than that of the common connector in the same transversal displacement. The second experiment shows that the efficiency of the tapered connector is higher than that of the common connector in the same frequency and amplitude.
