Taguchi method is a statistical approach to optimize the design parameters and improve the performance at a low cost. In this paper, Taguchi method is used as an attempt to analyze and optimize the Microring Resonators (MRRs) design, a multiple application device in optical communication systems. The silicon-on-insulator (SOI) wafer was selected as the medium of waveguide construction, with four control factors considered, namely width of rings and channels, radii of the microring, upper rib waveguide height and gap size. The analysis of variance (ANOVA) was adopted to analyze significant trends occurring on the Quality Factor (Q) and insertion loss (IL) performances under different sets of control factor combinations. Optimum parameter values were obtained and the confirmation experiments were also carried out. Upon optimization, the Q value improved to 1550 from 786 and IL decreased to 0.03 dB from 0.27 dB. It is verified via Taguchi analysis that not only the design constraints of the Microring Resonator can be identified, the performance of the design can be enhanced as well.
