Abstract

The performance optimization of Y -junction on Silicon-on-Insulator using Taguchi Method is presented. Several factors affecting the Y -junction structure such as the offset in the X direction (lx), offset in Z direction (lz), waveguide rib width and waveguide rib height have been studied for optimization purposes. The simulation has been done utilizing the OptiBPM software for device design and optical light propagation through the device in 3D at wavelength 1.55 μm. The four control factors were varied for 3 levels to perform 9 experiments using Taguchi method. Meanwhile, two noise factors chosen were varied for 2 levels to get readings of the output power from each arm for every row of experiment. The output power was optimized using signal-to-noise ratio (SNR) of 'larger-the-better.' It is concluded that the offset in the X direction (lx), was identified as having the major influence on the Y -junction performance by a percentage of 44%. The excess loss of the optimal design is reduced by 15% to 0. 05 dB. Hence, the optimized design is suitable to be used for the development of Mach-Zehnder Interferometer (MZI).
