In sequence, an experimental set-up preparation followed the numeric tool with the objective of identifying the lateral modes by using the frequency beat technique in the RF spectrum. A spectrum analyzer measured the signals emitted by the BALD using the fast Fourier transform (FFT) method.openAccesslaserssemiconductor diodessimulationcomputer codesNumerical simulation tool and experimental set-up for measuring the modal structure of a broad area semiconductor laser diodeTexto completo de evento10.1109/SBFotonIOPC54450.2022.99928430000-0002-9379-9530https://orcid.org/0000-0002-9379-9530
