Abstract
We investigate a millimeter-size Calcium fluoride (CaF2) microdisk resonator fabricated by a customized machining procedure. Stable coupling can be realized in our microdisk resonator coupled by a special tapered fiber. The mcirodisktaper coupling system exhibits an ultra-high Q factor up to ~108. In particularly, our coupling system exhibits a freespectral- range low to ~0.03 nm (~3.91 GHz). The frequency is suitable in microwave photonic systems, such as optical filters, optoelectronic oscillators, and optical gyroscopes for several technological applications such as radar, light-wave technology, frequency synthesis, detection inertial navigation system.
