Imaging junctions of waveguides
Inverse Problems & Imaging, 2021 In this paper we address the identification of defects by the Linear Sampling Method in half-waveguides which are related to each other by junctions. Firstly a waveguide which is characterized by an abrupt change of properties is considered, secondly the more difficult case of several half-waveguides related to each other by a junction of complex ...

Enhanced Terahertz Spectroscopy of a Monolayer Transition Metal Dichalcogenide
Advanced Functional Materials, EarlyView.An ad‐hoc engineered metallic surface is employed to perform enhanced terahertz spectroscopy of a monolayer transition metal dichalcogenide (TMD). Thanks to a local absorption boost of 104, this technique allows for the extraction of the phonon resonance features and effective permittivity of the 2D material, paving the way for the rational design of ...

Sensing of the acoustic signal by waveguides
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2008 The work is focused on the possibilities of accoustic emission (AE) signal sensing from surfaces inaccessible for commonly used sensors. The aim of the work is to verify the possibility of assembly of several measuring devices for maximalization of the ...

Low-loss single-mode integrated waveguides in soda-lime glass [PDF]
Applied Physics B, 122, 245 (2016), 2016 Low-loss single-mode optical waveguide fabrication process in extra-white soda-lime glass is demonstrated. Waveguiding structures are formed in bulk substrates employing femtosecond laser writing technology. The combination of a slit beam-shaping method and a multiscan fabrication process enables printing of waveguides with a well-defined symmetric ...
