Light guiding and optical resonances in ZnS microstructures doped with Ga or In
B. Sotillo, P. Fernandez, J. Piqueras
The high refractive index of ZnS (about 2.4 in the visible range) makes ZnS microstructures good candidates for the fabrication of light guides and resonant microcavities. Light gu…
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 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…
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…
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…
Dual regimes of ion migration in high repetition rate femtosecond laser inscribed waveguides
T. Toney Fernandez, B. Sotillo, J. del Hoyo +4
Ion migration in high repetition rate femtosecond laser inscribed waveguides is currently being reported in different optical glasses. For the first time we discuss and experimenta…
Controlling plasma distributions as driving forces for ion migration during fs laser writing
Toney Teddy Fernandez, Jan Siegel, Jesus Hoyo +3
The properties of structures written inside dielectrics with high repetition rate femtosecond lasers are known to depend strongly on the complex interplay of a large number of writ…
