Five-second coherence of a single spin with single-shot readout in silicon carbide

Christopher P. Anderson et al.

Summary: In this study, single-shot readout of single defects in silicon carbide (SiC) is achieved through spin-to-charge conversion, enabling mapping of the defect's spin state onto a long-lived charge state. The technique demonstrates over 80% readout fidelity and allows for measurement of long spin coherence times. Integration with semiconductor devices opens up opportunities for electrical readout.

Optical and Spin Properties of NV Center Ensembles in Diamond Nano-Pillars

Kseniia Volkova et al.

Summary: In this study, diamond nano-pillars were fabricated using electron beam lithography and reactive ion etching, and NV centers were successfully created. The lifetime of NV centers in the nano-pillars was found to be shorter, possibly due to the coupling between NV centers and interaction with other defects.

Infrared erbium photoluminescence enhancement in silicon carbide nano-pillars

R. A. Parker et al.

Summary: Enhancements of emission collection efficiency for Er3+ in 4H-SiC surface nano-pillars were demonstrated through optimized Er ion implantation, annealing strategies, and patterning with nano-pillars. The substitutional fraction of Er atoms in the SiC lattice is closely correlated with peak photoluminescence intensity, which is further enhanced through spatial wave-guiding in patterned surfaces. These results have broad applicability and demonstrate progress towards scalable fabrication of photonic quantum devices with enhanced emission characteristics.

Color Centers Enabled by Direct Femto-Second Laser Writing in Wide Bandgap Semiconductors

Stefania Castelletto et al.

Summary: By using femtosecond laser writing in silicon carbide and gallium nitride, vacancy-related color centers that emit photoluminescence from visible to infrared light can be generated. Large arrays of silicon vacancy defects with high localization within the confocal diffraction limit and minimal material damage can be produced using a 515 nm wavelength 230 fs pulsed laser. This study demonstrates the power-law scaling of the number of color centers formed with laser fabrication energy, indicating that the color centers are created by photoinduced ionization.

Using multi-polar scattering and near-field plasmonic resonances to achieve optimal emission enhancement from quantum emitters embedded in dielectric pillars

Faraz Ahmed Inam et al.

Summary: Recent research shows that a metal-dielectric pillar resonator scheme can achieve three orders of magnitude fluorescence enhancement, mainly due to the effects of multi-polar electromagnetic scattering resonances and near-field plasmonic field enhancement/confinement. By designing appropriate structures, it is possible to efficiently enhance and direct the emission of dipoles into far-field free space.

Understanding the photonics of single color-center emission in a high-indexed nano-pillar

Faraz A. Inam et al.

Summary: High-refractive index nano- and micropillars have been widely used to enhance the fluorescence properties of quantum emitters. However, a complete study of the electromagnetic dynamics and nanophotonics of single-photon emission within such pillars is currently lacking. The research on the electromagnetic dynamics of NCVSi centers in SiC micro-pillars showed a significant increase in fluorescence enhancement and collection efficiency compared to bulk SiC.
