Abstract: PURPOSE: An optical fiber core mode breaker and a manufacturing method thereof are provided to reduce loss by controlling the light propagating in a core mode and the light propagating in a cladding mode. CONSTITUTION: A laser is irradiated to a core(10) of an optical fiber(1) using a laser light source(3). The optical fiber comprises the core and a cladding(11) surrounding the core. The refractive index of the core is formed to be larger than the refractive index of the cladding. A focused ultra short pulse laser is irradiated to a cross section(100) of the core.
