论文摘要
集成的微型和纳米光学的光力学实验可以在单个声子级上操纵机械谐振器。连接这些结构需要详尽的技术限制可调性，灵活性和对多模式系统的缩放。在这里，我们使用纤维Fabry-Perot腔内内的3D激光器写的聚合物膜进行了空腔光学机械实验。达到了大约30 kHz的真空耦合强度，达到了基本的Megahertz机械模式。我们观察到机械谐振器对机械谐振器的光学弹簧调节，数十亿kHz超过其低温温度下的线宽。激光写作过程的极端灵活性使膜直接整合到微观腔中。直接的纤维耦合，其对耦合谐振系统的缩放功能以及耗散稀释结构的潜在实现以及电极的集成使其成为光纤尖端集成加速度计，光学上可调的多模式机械系统的有前途的平台，或直接使用Microwave的直接耦合系统以进行选择。
Integrated micro and nanophotonic optomechanical experiments enable the manipulation of mechanical resonators on the single phonon level. Interfacing these structures requires elaborate techniques limited in tunability, flexibility, and scaling towards multi-mode systems. Here, we demonstrate a cavity optomechanical experiment using 3D-laser-written polymer membranes inside fiber Fabry-Perot cavities. Vacuum coupling strengths of ~ 30 kHz to the fundamental megahertz mechanical mode are reached. We observe optomechanical spring tuning of the mechanical resonator by tens of kHz exceeding its linewidth at cryogenic temperatures. The extreme flexibility of the laser writing process allows for a direct integration of the membrane into the microscopic cavity. The direct fiber coupling, its scaling capabilities to coupled resonator systems, and the potential implementation of dissipation dilution structures and integration of electrodes make it a promising platform for fiber-tip integrated accelerometers, optomechanically tunable multi-mode mechanical systems, or directly fiber-coupled systems for microwave to optics conversion.
