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…
Tuning the surface energy of fluorinated diamond-like carbon coatings via plasma immersion ion implantation plasma-enhanced chemical vapor deposition with 1,1,1,2-tetrafluoroethane
Yuhan Tong, Maryam Zahedian, Aiping Zeng +6
We demonstrate an environmentally friendly and scalable method to create fluorine-doped diamond-like carbon (F-DLC) coatings using plasma immersion ion implantation plasma-enhanced…
Entangled two-photon absorption for the continuous generation of excited state populations in plasma
David R. Smith, Matthias Beuting, Daniel J. Den Hartog +4
Entangled two-photon absorption (ETPA) may be a viable technique to continuously drive an excited state population in plasma for high-bandwidth spectroscopy measurements of localiz…
Sub-nanometer-thick native sp2 carbon on oxidized diamond surfaces
Ricardo Vidrio, Cesar Saucedo, Vincenzo Lordi +4
Oxygen-terminated diamond has a wide breadth of applications, which include stabilizing near-surface color centers, semiconductor devices, and biological sensors. Despite the vast…
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…
