The embodiment of the invention provides a micro-ring modulator, an ultra-wind band modulator and a modulating system, and relates to the field of communication. The micro-ring modulator comprises a substrate layer and a waveguide layer located above the substrate layer; the substrate layer is used for supporting the waveguide layer; the waveguide layer comprises a micro-ring modulation array anda first waveguide and a second waveguide which are located on the two sides of the micro-ring modulation array, wherein the first waveguide and the second waveguide are symmetrically arranged; the micro-ring modulation array comprises at least two modulation units located on the same plane, each modulation unit corresponds to a resonant wavelength, different modulation units correspond to different resonant wavelengths, the distance between any modulation unit and the first waveguide is equal to the distance between the modulation unit and the second waveguide, and any modulation unit is usedfor modulating optical sig
