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…
Characterization of Nb22O54 microrods grown from niobium oxide powders recovered from mine tailings
B. Sotillo, F. A. Lopez, L. Alcaraz +1
In this work, the possibility of using niobium oxide recovered from tailings from the Penouta Sn-Nb-Ta deposit (located at the North of Spain) as starting material for growing micr…
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…
Chromium Oxide Formation on Nanosecond and Femtosecond Laser Irradiated Thin Chromium Films
L. Kotsedi, V. Furlan, V. Bharadwaj +9
Thin coatings of Chromium oxide have been used for applications as absorbing material in solar cells, as protections for magnetic data recording devices and as shields in flexible…
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…
