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…
Femtosecond laser inscription of nonlinear photonic circuits in Gallium Lanthanum Sulphide glass
María Ramos Vázquez, Belén Sotillo, Stefano Rampini +6
We report on femtosecond laser writing of single mode optical waveguides in chalcogenide Gallium Lanthanum Sulphide (GLS) glass. A multiscan fabrication process was employed to cre…
One-dimensional disordered photonic structures with two or more materials
Alessandro Chiasera, Luigino Criante, Stefano Varas +9
Here we would like to discuss the light transmission modulation by periodic and disordered one dimensional (1D) photonic structures. In particular, we will present some theoretical…
