Abstract
This paper attempts on optimizing the quality of Microring Resonator (MRR) based optical filter under various design parameters setting by using the Taguchi method in order to enhance the performance of the developed device. By using the Taguchi Method, tolerance analysis was carried out to investigate the effects of the device dimension changes on the overall performance. The orthogonal array, signal to noise ratio (S/N) and analysis of variance were employed to find the best parametric combination of design parameters setting, where the quality characteristics of interest are the quality factor and insertion loss, which are both important parameters in optical filter design. The results showed that the optimal combination of design parameters for insertion loss optimization are ring radii of 5.5 μm, gap separation distance of 100 nm, waveguide width of 400 nm and etching depth of 220 nm. Meanwhile, the optimal parametric design settings to optimize the Q-factor value are ring radii of 6.5 μm, gap separation distance of 120 nm, waveguide width of 420 nm and etching depth of 120 nm. Optimum results between both values are finally verified with the aid of confirmation experiments carried out using the Fullwave software. It was found that design tradeoffs between both values occur when the ring radii are 6.5 μm, gap separation distance is 100 nm, waveguide width is 400 nm and etching depth is 220 nm..
