The invention provides a three-dimensional asymmetric micro-cavity device for light field regulation and an integrated device thereof, the three-dimensional asymmetric micro-cavity device comprises a substrate and an optical micro-ring cavity located on the substrate, and the cross section of the optical micro-ring cavity gradually deflects according to the cross section deflection angle theta along with the change of the azimuth angle phi of a micro-ring, an end-to-end closed loop is formed; the cross section of the optical micro-ring cavity penetrates through the ring center in the axial direction of the cavity body of the micro-ring cavity, and the deflection angle theta of the cross section is an included angle between the connecting line direction of the midpoints of the short sides of the cross section and the axial direction perpendicular to the substrate. The technical scheme of the invention adopts a three-dimensional asymmetric structure, supports a light field to form resonance in an echo wall mode
