Abstract

Systems and methods for laser cleaving optical fibers are disclosed. In certain embodiments discussed herein, a ferrule of a fiber optic connector with an optical fiber disposed therein may precisely position an optical surface of the optical fiber when establishing an optical connection with another optical fiber. The optical surface may be thermally formed by laser beam(s) directed to an end face of the ferrule and to an end portion of the optical fiber extending therefrom. By having at least ninety (90) percent of the light incident on the ferrule as S-polarized light, the optical surface may be formed closer to the ferrule. This is because the laser beam may be more readily reflected away from the ferrule instead of being absorbed within the ferrule and thereby causing ferrule damage.
