Our current research focuses on advanced materials, active control techniques, integration with other photonic structures, and exploration of Anderson localization and polydisperse effects. Coherent feedback in cavity-enhanced random lasers is discussed as means to achieve specific emission characteristics, and emission at 1300 nm is shown for the first time.openAccesslasersrandomnessgelsglasswavelengthswave propagationTexto completo de evento10.1109/OMN/SBFotonIOPC58971.2023.102309750000-0002-9379-9530https://orcid.org/0000-0002-9379-9530
