Abstract
This paper focuses on the design and analysis of silicon photonic waveguides and optical micro-ring resonators, with a vision to advance next-generation computing, communication, and sensing technologies. Silicon photonics has emerged as a promising platform for integrating photonic components into existing semiconductor technology, enabling efficient on-chip communication and processing. Since the waveguides and resonators are primitive components in silicon photonics, this paper designs slot and rib waveguides along with optical ring resonators to operate at 1550 nm using COMSOL multiphysics and the analysis has been carried out in terms of the electric field excitation, propagation and transmission spectra. In addition, the fabrication process variations involving the performance dependency of process variation of optical ring resonator are analysed. It is found that even a single nm variation in the core width creates intolerable effects in resonance wavelength and hence it affects the complete operation of ring resonator. The outcomes of this research have the potential to shape the future of information processing, communication systems and sensing, paving the way for innovative solutions in the era of next-generation technologies.
