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…
Quantum micro-nano devices fabricated in diamond by femtosecond laser and ion irradiation
Shane M. Eaton, J. P. Hadden, Vibhav Bharadwaj +12
Diamond has attracted great interest as a quantum technology platform thanks to its optically active nitrogen vacancy center (NV). The NV's ground state spin can be read out optica…
Polarized micro-Raman studies of femtosecond laser written stress-induced optical waveguides in diamond
B. Sotillo, A. Chiappini, V. Bharadwaj +7
Understanding the physical mechanisms of the refractive index modulation induced by femtosecond laser writing is crucial for tailoring the properties of the resulting optical waveg…
Integrated waveguides and deterministically positioned nitrogen vacancy centers in diamond created by femtosecond laser writing
J. P. Hadden, V. Bharadwaj, B. Sotillo +11
Diamond's nitrogen vacancy (NV) center is an optically active defect with long spin coherence times, showing great potential for both efficient nanoscale magnetometry and quantum i…
Diamond photonics platform enabled by femtosecond laser writing
Belen Sotillo, Vibhav Bharadwaj, J. P. Hadden +14
We demonstrate the first buried optical waveguides in diamond using focused femtosecond laser pulses. The properties of nitrogen vacancy centers are preserved in the waveguides, ma…
Photonic glass-ceramics: consolidated outcomes and prospects
Brigitte Boulard, Tran T. T. Van, Anna Łukowiak +13
Transparent glass-ceramics are nanocomposite materials which offer specific characteristics of capital importance in photonics. This kind of two-phase materials is constituted by n…
