VictoriaMartín, Juan C.Atencia, JesúsVallés, Juan A.Coupled two-core integrated waveguides modal analysisART-2022-132771We present a modal analysis of coupled two-core integrated waveguides fabricated by femtosecond laser writing as a function of the core-to-core distance, illuminating position and input light wavelength. 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.2022http://zaguan.unizar.es/record/12439510.1088/1742-6596/2407/1/012016http://zaguan.unizar.es/record/124395oai:zaguan.unizar.es:124395Journal of Physics: Conference Series 2407, 1 (2022), 012016 [10 pp.]byhttp://creativecommons.org/licenses/by/3.0/es/info:eu-repo/semantics/openAccess
