Low Bend Loss, High Index, Composite Morphology Ultra-fast Laser Written Waveguides for Photonic Integrated Circuits
Andrew J. Ross-Adams, Toney T. Fernandez, Michael J. Withford +1
We demonstrate a novel, composite laser written 3D waveguide, fabricated in boro-aluminosilicate glass, with a refractive index contrast of 1.12 x 10^-2. The waveguide is fabricate…
Ultrafast laser inscribed waveguides in tailored fluoride glasses: An enabling technology for mid-infrared integrated photonics devices
T Toney Fernandez, B Johnston, S Gross +6
Zirconium fluoride (ZBLAN) glass, the standard material used in fiber-based mid-infrared photonics, has been re-designed to enable the fabrication of high index-contrast low-loss w…
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…
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…
Mid-infrared surface plasmon polariton chemical sensing on fiber-coupled ITO coated glass
Javier Martinez, Airan Rodenas, Magdalena Aguilo +3
A novel fiber-coupled ITO coated glass slide sensor for performing surface plasmon polariton chemical monitoring in the 3.5 um mid-IR range is reported. Efficient mid-IR fiber coup…
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…
