Abstract The invention provides an integrated optical filter which comprises an upper arm waveguide and a lower arm waveguide, the upper arm waveguide comprises a first upper coupling waveguide, an upper interference arm waveguide and a second upper coupling waveguide which are sequentially connected in the light path direction, and the lower arm waveguide comprises a first lower coupling waveguide, a lower interference arm waveguide and a second lower coupling waveguide which are sequentially connected in the light path direction. The upper interference arm waveguide comprises an upper bent waveguide assembly and an upper straight waveguide assembly which are connected with each other, the lower interference arm waveguide comprises a lower bent waveguide assembly and a lower straight waveguide assembly which are connected with each other, and the length of the upper straight waveguide assembly is not equal to that of the lower straight waveguide assembly; the arc length L1 of the upper bending waveguide assembly is e
