Multi-photon near-infrared emission saturation nanoscopy using upconversion nanoparticles

Upconversion nanoparticles offer the potential for deep tissue biological imaging. Here, Chen et al. develop super resolution optical imaging in the near-infrared for imaging with sub-50 nm resolution through almost 100 microns of tissue.

Versatile direct-writing of dopants in a solid state host through recoil implantation

Direct writing of active defects is a much sought-after step towards scalable quantum technologies. Here, the authors show a flexible approach by transferring momentum from an ion beam to thin films pre-deposited onto diamond surfaces (using films of Si, Ge, Sn or Pb) or fiber cores (using Eu).

Photonic crystal cavities from hexagonal boron nitride

Hexagonal boron nitride (hBN) is a layered van der Waals material showing promise for nanophotonics. Here, the authors design hBN photonic crystal cavities with quality factors exceeding 2000, and further demonstrate deterministic tuning of individual cavities by minimally-invasive electron beam induced etching.

All-optical control and super-resolution imaging of quantum emitters in layered materials

The photophysical properties of quantum emitters in layered van der Waals materials are receiving growing attention as they could be leveraged for nanophotonics applications. Here, the authors devise a two-laser super-resolution imaging setup capable of observing highly non-linear emission from hBN emitters.

Quantum emission from hexagonal boron nitride monolayers

Single-photon emission at room temperature can be achieved with hexagonal boron nitride due to electron and hole confinement in vacancy-related defects.

Optically addressable spin defects coupled to bound states in the continuum metasurfaces

Previous research reported enhanced emission from spin defects in hBN by coupling to optical resonators; however, this approach has limited scalability. Here the authors use a monolithic metasurface featuring quasi bound states fabricated from hBN to enhance photoemission and optical spin-readout efficiency of defects in the same material.

Identifying carbon as the source of visible single-photon emission from hexagonal boron nitride

Comparison of hexagonal boron nitride samples grown with different techniques and with varying carbon-doping content provides evidence that the defects emitting single photons in the visible range are carbon related.

Initialization and read-out of intrinsic spin defects in a van der Waals crystal at room temperature

An ensemble of spins associated with an intrinsic defect of two-dimensional hexagonal boron nitride is shown to be optically addressable, allowing spin polarization of its triplet ground state and providing evidence of spin coherence.
