The invention provides a micro lens and optical waveguide power divider integrated component and a manufacturing method thereof. In the invention, a hemispherical focusing micro lens array is formed on a glass substrate by the application of an ion exchange technology and further femtosecond laser is utilized to induce to change the refractive index inside the glass substrate to form the optical waveguide power divider with the micrometer width so as to realize integration of two basic micro optical components, namely a micro lens and the optical waveguide power divider, onto one glass substrate, realize alignment and coupling of the micro lens and the optical waveguide, generate a micro optical integrated device with the optical performance and fill a technical gap of the field.
