A practical guide to feedback control for Pound-Drever-Hall laser linewidth narrowing
Wance Wang, Sarthak Subhankar, Joseph W. Britton
The Pound-Drever-Hall (PDH) technique for laser linewidth narrowing is widely used by AMO experimentalists. However, achieving a high-performance PDH locking requires substantial e…

Coupling a Fabry-Pérot Cavity to a Single-Mode Optical Fiber Using a Metalens
Wance Wang, Wenqi Zhu, Amit Agrawal +1
Efficient coupling of light from an optical cavity to a single-mode fiber is required in a range of quantum technologies. In this work we consider the coupling of a high-finesse ma…

Can TCOs Transform Cavity-QED?
Wance Wang, Dhruv Fomra, Amit Agrawal +2
Transparent conductive oxides (TCO) enable confinement of charge-sensitive ions and Rydberg atoms proximal to dielectric structures including waveguides and photon detectors. Howev…
