We previously demonstrated a new resonator device structure that achieves Q-factors well above those currently realisable. The new structure consists of a microwave cavity, where the enclosure walls consist of distributed Bragg reflectors (DBRs) in three dimensions, made of low-loss sapphire. Theoretical analysis has demonstrated that the resonator's performance is critically dependent upon accurate alignment of the DBR components, thereby maintaining the desired symmetry of the resonant… CONTINUE READING
