(Integrated Diffractive Mirrors (IDM) Ion Traps)
Abstract
Future progress in trapped-ion quantum information processing (QIP) depends on the miniaturization and integration of ion trapping technologies. With large-scale microfabrication of trapping structures now well advanced, the trapped-ion QIP community has recently turned to the task of integrating light collection optics with traps in a scalable fashion. We consider scalability to be defined by the ability to add additional lenses to collect light from additional ions without reducing performance or substantially increasing complexity (e.g., reduced collection efficiency and increased optomechanical alignment requirements, respectively). We report here on the development and preliminary testing of the first collection optic integrated with a microfabricated ion trap that satisfies these criteria for scalability. We demonstrate that these integrated optics are readily fabricated using standard processes, are robust to normal bakeout procedures for ion traps (200C), and are capable of collecting ion fluorescence comparable to state-of-the-art non-scalable objective systems. With dozens of trap die completed and three packaged and tested, we expect testing and application of these optics to continue well beyond the completion of the IDM program.
