On-chip single-photon subtraction by individual silicon vacancy centers in a laser-written diamond waveguide
Michael K. Koch, Michael Hoese, Vibhav Bharadwaj +6
Modifying light fields at single-photon level is a key challenge for upcoming quantum technologies and can be realized in a scalable manner through integrated quantum photonics. La…
An integrated magnetometry platform with stackable waveguide-assisted detection channels for sensing arrays
Michael Hoese, Michael K. Koch, Vibhav Bharadwaj +8
The negatively-charged NV-center in diamond has shown great success in nanoscale, high-sensitivity magnetometry. Efficient fluorescence detection is crucial for improving the s…
Laser-Inscribed Diamond Waveguide Resonantly Coupled to Diamond Microsphere
Nurperi Yavuz, Mustafa Mert Bayer, Hüseyin Ozan Cirkinoğlu +6
An all-diamond photonic circuit was implemented by integrating a diamond microsphere with a femtosecond-laser-written bulk diamond waveguide. The near surface waveguide was fabrica…
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…
Femtosecond laser written diamond waveguides - a step towards integrated photonics in the far infrared
Vibhav Bharadwaj, Yuchen Wang, Toney Teddy Fernandez +3
A first demonstration and complete characterization of mid-infrared waveguides in diamond are reported in detail. Waveguides were designed for 2.4 um and 8.6 um waveguiding, with t…
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…
