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…
