A rotating optical resonator, a waveguide and a method of use of waveguide are disclosed. The rotating optical resonator may include at least two modes of different resonant frequencies shiftable towards each other by reducing a magnitude of rotation rate, said modes being joinable into a substantially degenerate mode by setting substantially zero rotation rate, said resonator being of an optical size smaller than five wavelengths of the substantially degenerate mode. The waveguide may include a plurality of coupled evenly degenerate split mode resonators, the split of the modes forming a stop band in a resonant band of the waveguide, the stop band of the waveguide thereby being changeable by changing an angular velocity of the waveguide while the vector of the angular velocity is non-parallel with respect to the waveguide.
