“…Figure 1(b) depicts a structure consisting of N non-uniform coupled micro-ring resonators. The spacing between the waveguides and the adjacent rings as well as between consecutive rings determines the coupling coefficients κ i of the various coupling regions [8,22]. There are a total of N+1 coupling regions in the structure and κ 1 refers to the coupling coefficient between the input waveguide and the first ring, κ i for 2iN stand for the coupling coefficient between the (i − 1)th and the ith rings while κ Ν+1 is the coupling coefficient between the last ring and the output waveguide.…”

“…Using reciprocity relations [9], it is possible to rigorously relate the amplitudes of the modes at the input and the output of each interaction region through the coupling coefficients. The coupling coefficients κ i are determined by the electric field profiles of the modes of the isolated waveguides and can be calculated approximately analytically assuming an effective index 2D approximation [8] or numerically using rigorous mode analysis and numerical integration of the modal field overlap near the coupling region [22].…”

“…This is why, the CMT framework is used throughout this thesis as a basis for the calculation of the transfer function. It is interesting to note that evidence in the literature [110] suggests that FDTD and coupled mode analysis agree very well for the coupling region of the ring even if a full-blown 3D model is assumed.…”
