Author(s): M. Alonso-Orts, E. Nogales, J. M. San Juan, M. L. Nó, J. Piqueras, and B. Méndez Widely tunable nano- and microscale light emitters based on a single material do not suffer from alloying-induced defects, and thus are very desirable for photonic devices. Suitable materials are scarce, though. This study of Bragg-reflector microcavities in Ga 2 O 3 :Cr microwires, with an intense red-infrared luminescence band, reveals strongly modulated, tunable spectra. Experimental data, analytical calculations, and simulations show good agreement, in a comprehensive analysis of propagated and confined modes and reflectivity along the emission band. This microcavity approach to tunable light sources is promising for applications in optoelectronics and photonics. [Phys. Rev. Applied 9, 064004] Published Thu Jun 07, 2018
