In this work, we have used an optical microring-based resonator, and developed a Multiphysics finite element model of this resonator for ultrasensitive biomolecule and nanoparticle detection. We applied an input tunable laser light at the input node of the straight form waveguide at a wavelength of 1.55 μm and monitored the transmitted light at the output node. During this process, we recorded the transmission spectrum and located the exact position of the resonance wavelengths shifted towards higher wavelength value (red shift). A linear correlation was observed, between increasing the radius of the microring and the resonance wavelength red shift. Additionally, we have shown that we could detect resonance value shifts for very small changes in the microring radius, as low as 10 nm.
