    2020-4-1 · A typical coupling approach is the dual waveguide coupling of a ring resonator. After the incident light is input from the “input port”, a part of the light satisfying the resonance condition is coupled into the microring through the input straight waveguide, and part of the light is output through the “through port” shown in Fig. 7(a). The light coupled into the microring cycles within the resonator, and a portion …

  • Extracting coupling and loss coefficients from a ring ...

    A method is developed for extracting the coupling and loss coefficients of ring resonators from the peak widths, depths, and spacings of the resonances of a single resonator. Although the formulas used do not distinguish which coefficient is coupling and which is loss, it is shown how these coefficients can be disentangled based on how they vary with wavelength or device parameters.
