The Y2SiO5 (YSO) crystal is a dielectric material with biaxial anisotropy with known values of refractive index at optical frequencies. It is a well-known rare-earth (RE) host material for optical research and more recently has shown…
Optical networks that distribute entanglement among quantum technologies will form a powerful backbone for quantum science but are yet to interface with leading quantum hardware such as superconducting qubits. Consequently, these systems…
Dielectric resonators are key components for many microwave and millimetre wave applications, including high-Q filters and frequency-determining elements for precision frequency synthesis. These often depend on the quality of the dielectric…
