In order to do that we use the correlation filter method, implementing the computer generated holograms in a phase-only spatial light modulator. Due to the two-core waveguide symmetry, we prove it is not necessary to encode the complex amplitude in a phase-only device as long as the cores are not strongly coupled. A comparison between experimental and numerical modal weights is presented, showing that simple phase-only match filters allow the modal decomposition of two-core waveguides output beams. info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 0.183 2022 Physics and Astronomy (miscellaneous) 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Collados, M.
