Universidad de Zaragoza (orcid)0000-0001-6575-168X Amplification of stimulated light emission in arrays of nanoholes by plasmonic absorption-induced transparency 2021 Access copy available to the general public Unrestricted Absorption induced transparency is an optical phenomenon that occurs in plasmonic nanostructures when materials featuring narrow lines in their absorption spectra are deposited on top of it. First reported in the visible range for metallic arrays of nanoholes, using dye lasers as covering, it has been described as transmission peaks unexpectedly close to the absorption energies of the dye. In this work, amplification of stimulated light emission is numerically demonstrated in the active regime of absorption induced transparency. Amplification can be achieved in the regime where the dye laser behaves as a gain material. Intense illumination can modify the dielectric constant of the gain material in a short span of time and thus the propagation properties of the plasmonic modes excited in the hole arrays, providing both less damping to light and further optical feedback that enhances the stimulated emission process. info:eu-repo/grantAgreement/ES/MCIU/MAT2017-88358-C3-2-R info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 3.833 2021 OPTICS 28 / 101 = 0.277 2021 Q2 T1 1.233 2021 Atomic and Molecular Physics, and Optics 2021 Q1 7.3 2021 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 2002 647 Universidad de Zaragoza Dpto.
