Abstract
Wavelength-sized microdisk resonators were fabricated on a single crystalline 4H-silicon-carbide-on-insulator (4H-SiCOI) platform. By carrying out micro-photoluminescence measurements at room temperature, we show that the microdisk resonators support whispering-gallery modes (WGMs) with quality factors up to $5.25 \times {{10}^3}$ and mode volumes down to $2.61 \times {(\lambda /n)^3}$ at the visible and near-infrared wavelengths. Moreover, the demonstrated wavelength-sized microdisk resonators exhibit WGMs whose resonant wavelengths are compatible with the zero-phonon lines of silicon related spin defects in 4H-SiCOI, making them a promising candidate for applications in cavity quantum electrodynamics and integrated quantum photonic circuits.
