    Proposed design of the human-like micro stereo sensors system, where N1 to N6 are node 1 to node 6 for eye, ear, tongue, body, nose, and brain. R1 and R2 are radii of microring resonators. κ1 to κ4 are coupling coefficients. The optical fields for input, throughput, add, and drop ports are given by Ein, Eth, Eadd, and Edr, respectively.
