Design and implementation of an integrated optical coupler by femtosecond laser written-waveguides in LiNbO3
(Elsevier, 2020-03)
This work presents a particular application corresponding to waveguides manufactured by the femtosecond laser micro-machining technique. More specifically we have conducted the study, design, simulation and implementation ...
Polarization behaviour of femtosecond laser written waveguides in lithium niobate
(Elsevier Science, 2015-06)
In this work, we analysed the polarization of guided light in femtosecond laser written waveguides. The studied waveguides were performed with different laser pulse energies in an x-cut lithium niobate crystal. The guided ...
Femtosecond laser micro-patterning of optical properties and functionalities in novel photosensitive silver-containing fluorophosphate glasses
(2019-08-01)
Silver-containing glasses are promising candidates for photonic applications, due to the potentiality of spectroscopic properties of silver nanoclusters (NC's)and/or silver metallic nanoparticles. In this framework, ...
μ-Raman spectroscopy characterization of LiNbO3 femtosecond laser written waveguides
(American Institute of Physics, 2012-12)
In this paper, we present an iterative method which merges experimental μ-Raman measurements and numerical simulations to describe femtosecond written waveguides in LiNbO3 crystals. This method is based on the deformation ...
Femtosecond laser-written double line waveguides in germanate and tellurite glasses
(Society of Photo-optical Instrumentation Engineers, 2018)
Testing a novel μ-Raman method to retrieve refractive index and density field from femtosecond laser-written optical waveguides
(Springer, 2016-11)
In this work, we analysed the refractive index field and other local material properties of femtosecond laser-written waveguides properly combining a novel and direct Raman strategy, waveguides coupling and instrumented ...
