Microelectromechanical-System-Based Design of a High-Finesse Fiber Cavity Integrated with an Ion Trap

Abstract

The ion-cavity quantum interface is an important building block for tomorrow's quantum networks, but miniaturizing such devices remains an outstanding challenge. This study introduces and characterizes an on-chip design that uses microelectromechanical-systems (MEMS) technology to integrate a fiber-based optical resonator with an ion trap. Simulations show that the device's performance is expected to be similar to that of much larger existing systems, and that it is compatible with strong ion-cavity coupling. A MEMS approach thus offers a promising route to scalable quantum networks based on miniaturized, fast, high-fidelity interfaces.
