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…
Optical and microstructural studies of femtosecond laser treated amorphous germanium thin coatings
L. Kotsedi, A. Abdelmalek, V. Bharadwaj +8
The study of the relaxation mechanism of amorphous germanium after femtosecond laser irradiation is presented in this work. In particular, a thin germanium coating was deposited on…
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.…
