The first theoretical models of the propagation of an electromagnetic field in a waveguide date back to the second half of the 19th century (Hertz, Debye, Rayleigh). The technological fallout for long ...

Upon propagation along nonlinear waveguides, laser light can be converted nonlinearly with respect to its spectral and spatial composition. In four-wave mixing (FWM) the spectral or spatial ...

The scattering of an acoustic wave propagating in a non-uniform waveguide is inspected by revisiting improved multimodal methods in which the introduction of additional modes, so-called boundary modes ...

In a paper published in the journal Advanced Photonics, researchers demonstrated broadband nonlinear frequency conversion using mode-hybridization on X-cut thin film lithium niobate. They achieved ...
