Witryna1 lis 2024 · Hermite-Gaussian (HG) and Laguerre-Gaussian (LG) modes are both eigen solutions of the paraxial wave equation deduced from Maxwell’s equations by means of the paraxial approximation [1], [2] [Orlov, 2007 #368]. The first modes are in rectangular coordinates and the second ones are in cylindrical coordinates. HG beams are well … WitrynaAbstract Although Hermite functions have been studied for over a century and have been useful for analytical and numerical solutions in a myriad of areas, ...

Witryna8 kwi 2024 · We propose a Hermite–Gaussian (HG) mode-demulti-plexing hybrid (MDH) for coherent detection of mode-division multiplexed signals. The MDH, which … WitrynaModes of higher transverse order can be described e.g. by Hermite–Gaussian or Laguerre–Gaussian functions. In any case, the deviation from a Gaussian beam shape can be quantified with the M 2 factor. A Gaussian beam has the highest possible beam quality, which is related to the lowest possible beam parameter product, and …
Witryna29 wrz 2024 · The Hermite-Gaussian (HG) modes, sometimes also referred to as transverse electromagnetic modes in free space, form a complete and orthonormal basis that have been extensively used to describe optical fields. In addition, these modes have been shown to be helpful to enhance information capacity of optical communications … Witryna1 wrz 2007 · Based on the Snyder-Mitchell model in the Cartesian coordinate system, exact analytical Hermite-Gaussian (HG) solutions are obtained in strongly nonlocal nonlinear media. The comparisons of analytical solutions with numerical simulations of the nonlocal nonlinear Schrodinger equation show that the analytical HG solutions are …
