Abstract
Ring resonators are among the most fundamental and versatile components of photonic integrated circuits (PICs), with proven applications in sensing, filtering, and wavelength demultiplexing. Despite their simple geometry, based on a waveguide loop coupled to a bus waveguide, ring resonators continue to offer new opportunities for enhancing performance and integrating functionality of optical systems. In this work, we present recent progress in developing silicon nitride (SiN)-based ring resonator structures integrated with metal–insulator–metal (MIM) plasmonic waveguides for refractive index sensing applications, fabricated at the Centre for Advanced Materials and Technologies (CEZAMAT) and the Institute of Microelectronics and Optoelectronics (IMiO), Warsaw University of Technology.

I’m a graduate of Photonics from the Faculty of Physics of the Warsaw University of Technology (WUT) and currently a PhD student at WUT, Institute of Microelectronics and Optoelectronics. Both my bachelor's and master's theses were related to fiber-optic sensors. Currently, my research focuses primarily on photonic integrated circuits (PICs) with a strong emphasis on sensing applications. My main interests focus on passive silicon nitride (SiN) PICs, both from the perspective of simulations, characterization, and technological insights, with a specific interest in implementing plasmonic-enhancement effects in PICs for sensing applications.
