Abstract

Optical telecommunications are among the vital components in the field of modern communication in this day and age as it acts as the main backbone for many of the internet activities; social media, cloud services or even space engineering. It consists of several kinds of components that could help deliver the best services for the use of either corporate or consumer-level users. One of the essential components for data delivery connectivity is its filtering function. Optical Microring Resonator (OMR) is one of the optical telecommunications components commonly applied as wavelength filtering function. Hence, in this project, the Optical Microring Resonator (OMR) filter with polymer grafting material (PMMA) coating was designed and optimized to predict its potential as wavelength filtering devices. The optimization was focused on the design parameters such as its doped polymer thickness, the variation of gap separation, dissimilar bus and ring width waveguide combination to achieve the best output in terms of lower Insertion Loss (IL) and Extinction Ratio per cent (Through) for Wavelength-Division Multiplexing (WDM) applications specifically for the use of C-Band network. The OptiFDTD 15.0 software was employed in the design and the characterization process. Upon completion, it was found that the optimized design at the radius of 10 (um), 0.055 (um) thickness of PMMA applied and dissimilar width of 400 (nm) straight and 800 (nm) ring waveguide could be able to achieve 0.0099728 dB of Insertion Loss at 15° phase shift and 31.62% Extinction Rate.
