Coherent control of optical lattices and optical unit cells in atomic medium by counter propagation of Laguerre Gaussian beams

Year: 2025

Type: article

Abstract: This manuscript explores the coherent control of optical lattices and optical unit cells. Optical lattices are formed by the counter-propagation of Laguerre Gaussian beams within an atomic medium. Variations in absorption and the refractive index along the x and y axes provide insight into the confined modes of the optical lattice and its unit cells, from which we can extract information about mode confinement. Density plots of the absorption spectrum and refractive index reveal the presence of unit cells in both the valley and peak regions of the counter-propagating Laguerre Gaussian standing wave fields. In this manuscript, we control the Wigner and cubic-type unit cells of optical lattices with lattice parameters [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text].
