Vector Theory for the Scattering of TM-polarized Hermite-Gaussian Electromagnetic beams by a Double Metallic Slit

Gaussian, Hermite-Gaussian, and Laguerre-Gaussian beams: A primer

The paper aims at presenting a didactic and self-contained overview of Gauss-Hermite and Gauss-Laguerre laser beam modes. The usual textbook approach for deriving these modes is to solve the Helmoltz electromagnetic wave equation within the paraxial approximation. Here, a different technique is presented: Using the plane wave representation of the fundamental Gaussian mode as seed function, all...

Numerical Calculation of Coupling Efficiency for an Elegant Hermite-Cosh-Gaussian Beams

The ABCD matrix method is used to simplifying the theoretical coupling efficiency calculation of Elegant Hermite-Cosh-Gaussian (EHChG) laser beams to a Single Mode Fiber (SMF) with a quadric lens formed on the tip. The integrals of coupling efficiency relation are calculated numerically by Boole method. Meanwhile, the structure parameters of surface-lensed fiber are optimized in numerical simul...
