Abstract: PURPOSE: An optical fiber fabrication using an asymmetric refractive index of a multi-mode coupler is provided to have more simple using asymmetric refractive index at a multi-mode interference coupler. CONSTITUTION: An input waveguide(11) is connected to the first side of a multi-mode interference coupler(10). An output waveguide(12) is connected to the second side opposite to the first side of the multi-mode interference coupler. A thin film heater(20,21,22) heats a predetermined portion of the multi-mode interference coupler. An optical path is changed as an index of refraction of the coupler becomes asymmetric when the predetermined portion of the multi-mode interference coupler is heated. The thin film heater is overlapped with the predetermined portion of the third side of the coupler, which is one of two corners of the third side which is not adjacent to the first and second sides.
