GLASSY MATERIALS AND LIGHT: PART 2
(Soc Brasileira Quimica, 2016-04-01)
In this second part it will be discussed some photonic applications of glassy and glass ceramic thin films which can be used as planar waveguides. Some photonic applications require certain specifications of glass, which ...
Buried waveguides in Nd:YLF crystals obtained by femtosecond laser writing under double line approach
(Springer, 2013-03)
In this paper, we present buried waveguides fabricated by fs laser writing in Nd3+ doped YLF crystal under double line approach (Miura et al. in Appl. Phys. Lett. 71:3329?3331, 1997). The waveguides were made by focusing ...
α[sbnd]Ag2WO4 under microwave, electron beam and femtosecond laser irradiations: Unveiling the relationship between morphology and photoluminescence emissions
(2022-05-15)
In this study, the α-Ag2WO4 samples were successfully synthesized combined two methods, co-precipitation and microwave-assisted hydrothermal. Later, two different irradiation processes: electron beam and femtosecond laser ...
Nonlinear absorption spectrum in perylene derivatives
(2005-10-31)
Knowledge about nonlinear absorption spectra of materials used in photonic devices is of paramount importance in determining their optimum operation wavelengths. In this work, we have investigated the two-photon absorption ...

Femtosecond light distribution at skin and liver of rats: analysis for use in optical diagnostics
(WILEY-V C H VERLAG GMBH, 2010)
In this study we investigated the light distribution under femtosecond laser illumination and its correlation with the collected diffuse scattering at the surface of ex-vivo rat skin and liver. The reduced scattering ...
Light coupling in single-track guiding structures obtained by femtosecond laser writing in lithium niobate
(Optical Society Of America, 2014-03)
n this Letter we present a study of light coupling into a pair of Type II waveguides made of lithium niobate crystals by using femtosecond laser writing. Simulations based on the beam propagation method and optical fiber ...
