Dr. Oracio Barbosa García

Centro de Investigaciones en Optica (CIO), León Gto. México


Dr. Oracio Barbosa graduated in Physics in 1975 at the University of Michoacan in México and obtained the M. Sc. and Ph. D. in physics at the Boston College, Chestnut Hill Massachusetts. U.S.A., in 1982 and 1993. Before he joined the Centro de Investigaciones en Optica (CIO) in 1985, he was teaching basic courses on physics and mathematics at the University of Michoacan. At CIO he joined the Quantum Optics group and in 1998 he founded and led the Research group on optical properties of materials (GPOM), initially centered on the study of non-radiative energy transfer processes among rare earth ions. Currently the group focuses on the study of linear and non-linear optical properties of inorganic and organic photonic materials, both in bulk and nano-structured. The GPOM develops instrumentation and applications of spectroscopic techniques --absorption, Raman and laser induced breakdown-- to bio-photonics, food industry, pharmaceutics, shoe and paint industries and archeology. It has recently received funding from the Mexican Bureau for Energy (Secretaría de Energía de México) and the CONACyT to develop organic solar cells with a power conversion efficiency of 6%. Currently, the efficiency obtained by the group is around 4% and by using a new vacuum deposition system and glove boxes, they aim to reach 6% efficiency within a year. Furthermore, by using plasmonics and trapping processes the group expects to exceed that efficiency value. Dr. Barbosa promoted the creation of the SPIE-Mexico chapter in 2002; from 2002-2005 he was the president of the Mexican Academy of Optics (Academia Mexicana de Optica); since 2005 he serves as the academic advisor of the SPIE and OSA graduate students chapters at CIO ; he also promoted the realization of the Mexican Meetings: "Optics in Industry" and "Optics and Photonics" in 2000 and 2012, respectively.
