Femtosecond laser-written nano-ablations containing bright antibunched emitters on gallium nitride
Yanzhao Guo, Giulio Coccia, Vibhav Bharadwaj +5
Femtosecond laser-writing offers distinct capabilities for fabrication, including three-dimensional, multi-material, and sub-diffraction-limited patterning. In particular, demonstr…
Enhanced quantum magnetometry with a laser-written integrated photonic diamond chip
Yanzhao Guo, Giulio Coccia, Vinaya Kumar Kavatamane +8
An ensemble of negatively charged nitrogen-vacancy centers in diamond can act as a precise quantum sensor even under ambient conditions. In particular, to optimize thier sensitivit…
Vector Magnetometry Using Shallow Implanted NV Centers in Diamond with Waveguide-Assisted Dipole Excitation and Readout
Sajedeh Shahbazi, Giulio Coccia, Argyro N. Giakoumaki +8
On-chip magnetic field sensing with Nitrogen-Vacancy (NV) centers in diamond requires scalable integration of 3D waveguides into diamond substrates. Here, we develop a sensing arra…
Laser-written waveguide-integrated coherent spins in diamond
Yanzhao Guo, John P. Hadden, Federico Gorrini +12
Quantum emitters, such as the negatively charged nitrogen-vacancy center in diamond, are attractive for quantum technologies such as nano-sensing, quantum information processing, a…
Determining Strain Components in a Diamond Waveguide from Zero-Field ODMR Spectra of NV Center Ensembles
M. Sahnawaz Alam, Federico Gorrini, Michał Gawełczyk +13
The negatively charged nitrogen-vacancy (NV) center in diamond has shown great potential in nanoscale sensing and quantum information processing due to its rich spin physics.…
