The invention discloses an adjustable integration optical filter with an array type micro-resonator, relating to an optical filter and providing a realizable array type micro-resonator based on the existing micro-nano processing technique. The optical filter is provided with a substrate, a lower layer metallic film is arranged on the substrate, a dielectric layer is arranged on the lower layer metallic film, a metal grating layer is embedded in the middle of the dielectric layer and an upper layer metallic film is arranged on the dielectric layer. The metal grating layer is provided with a plurality of array units and the cycle of the metal grating in different array units is different. As the layer of dielectric layer embedded with the metal grating is arranged between the two layers of metallic films on the substrate and the metal grating in different integration units on a chip plane has different cycles, the equivalent refractive index in different units is regulated. When light wave goes through the adjustable integration optical filter of array type micro-resonator, different array units have different resonance wavelengths, therefore, a transmission passband is formed within certain wave spectrum width close to the resonance wavelength for the purpose of filtering.
