Fig. 1. 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 E_in, E_th, E_add, and E_dr, respectively.
