Abstract
An efficient method to mount a coupled silica microsphere and tapered fiber system is proposed and demonstrated experimentally. For the purpose of optomechanical studies, high-quality-factor optical (Qo ～ 108) and mechanical modes (Qm ～ 0.87 × 104<)sup>) are maintained after the mounting process. For the mounted microsphere, the coupling system is more stable and compact and, thus, is beneficial for future studies and applications based on optomechanical interactions. Especially, the packaged optomechanical system, which is tested in a vacuum chamber, paves the way toward quantum optomechanics research in cryostat.
