Metasurfaces for neutral-atom trapping
Chengyu Fang, Minjeong Kim, Mark Saffman +2
Trapped neutral atoms are one of the leading platforms for quantum information technologies, in particular for quantum computing, but scaling them to array sizes needed for utility…
Silicon-on-sapphire metasurfaces generate arrays of dark and bright traps for neutral atoms
Chengyu Fang, Minjeong Kim, Hongyan Mei +10
We demonstrated crystalline silicon-on-sapphire (c-SOS) metasurfaces that convert a Gaussian beam into arrays of complex optical traps, including arrays of optical bottle beams tha…
Efficient simulation framework for modeling collective emission in ensembles of inhomogeneous solid-state emitters
Qingyi Zhou, Wenxin Wu, Maryam Zahedian +2
An efficient simulation framework is proposed to model collective emission in disordered ensembles of quantum emitters. Using a cumulant expansion approach, the computational compl…
Broadband light extraction from near-surface NV centers using crystalline-silicon antennas
Minjeong Kim, Maryam Zahedian, Wenxin Wu +9
We use crystalline silicon (Si) antennas to efficiently extract broadband single-photon fluorescence from shallow nitrogen-vacancy (NV) centers in diamond into free space. Our desi…
Atomic magnetometry using a metasurface polarizing beamsplitter in silicon on sapphire
Xuting Yang, Pritha Mukherjee, Minjeong Kim +9
We demonstrate atomic magnetometry using a metasurface polarizing beamsplitter fabricated on a silicon-on-sapphire (SOS) platform. The metasurface splits a beam that is near-resona…
