The purpose of this study was to design a model for microring resonators (MRRs) for biochemical detection. As a model, two types of MRRs were proposed. The Lumerical application software was used to optimize and analyze the design of MRRs device. Several parameters influencing the detection process were investigated, including the gap separation, the ring radius, the waveguide width and the etching depth dimension of MRRs. The results showed that these parameters highly influenced the condition of MRRs. The optimum parameters yielding optimum detection of biochemical are 4.5 um, 90 nm, 470 nm and 220 nm, corresponding to ring radius, separation gap, waveguide width and etching depth, respectively. The both models of MRRs proposed in this paper yield large values of FSR (free spectral range) and Q-factor therefore are suitable for biochemical detection.
