By spectral phase modulation of the excitation pulse, we investigated the coherent control of two-photon absorption in organic compounds. Depending on the molecules’ two-photon absorption relative to the pulse wavelength, different levels of control can be achieved.
The National Institute of Photonics activities are dedicated to expand world-class photonics research and education in Brazil.
The National Institute of Photonics – INFO, is one of the National Institutes approved under the INCTs program (National Institutes of Science and Technology) supported by the MCTIC/CNPq/CAPES/FAPs in Brazil, now in its second phase (2016-2022).
Photonics has been defined as the science and technology of light. It deals with the generation, detection, harnessing and applications of light, whose basic unit if the photon. As already recognized, photonics is everywhere around us: from sunlight based photovoltaics to optical communications and health; from materials processing to everyday products like DVD players and mobile phones. More than 34 Nobel Prizes were given to scientists due to Optics and Photonics related scientific and technological achievements.
Our mission is to expand world class photonics research, innovation and education in Brazil.
The INFO is formed by 21 institutions, with 05 institutions with research groups consolidated in the theme of photonics and its applications, 05 institutions with emerging groups. In addition to these 10 institutions that form the basic nucleus of the INFO, 11 institutions are considered associated, since they have one or two researchers working on the INFO sub-projects in collaboration with consolidated groups.
As shown on the map, these 21 institutions are scattered in 05 Brazilian states, being 07 in the Northeast, 13 in the Southeast and 01 in the Midwest.
One of the INFO strengths is its comprehensive program of international scientific collaboration. Through common scientific projects, the international mobility of researchers / students between INFO members and their international partners makes the research environment highly dynamic.
The map of international collaborations shows the diversity of Countries with which there is collaboration, whose details are shown in the table below.
The INFO research program is shown in the diagram below, and has work in 03 sub-areas of the photonics: Nonlinear Photonics, Devices and Applications; Biophotonics and Optomicrofluidics.
In these three sub-areas, 50 sub-projects are led by the INFO researchers, with 23 sub-projects in Non-Linear Photonics, Devices and Applications; 17 sub-projects in Biophotonics and 10 sub-projects in Optomicrofluidics.
Nonlinear Photonics can be defined as the junction of some traditional areas of optics, particularly nonlinear optics (read more in https://en.wikipedia.org/wiki/Nonlinear_optics), whose scientific development has generated devices and applications in the field of photonics, such as sources of supercontinuum generation, optical harmonics or optical amplifiers in bulk or integrated devices
Biophotonics (read more at http://www.photonics4life.eu/P4L/About-Photonics4Life/What-is-Biophotonics) is a multidisciplinary area of interface between photonics and biomedical areas, with important social impact.
Optomicrofluidics (read more at https://www.elveflow.com/microfluidic-tutorials/microfluidic-reviews-and-tutorials/microfluidics/) employs photonics in conjunction with microfluidics, whose applications range from use in sensors to type lab-on-chips.
The INFO's main resource is its human capital, made up of a permanent team of senior researchers and young researchers, post-docs, doctoral students, masters and scientific initiation.
Currently counting 41 permanent researchers in the 10 institutions that form the base of the INFO, 22 researchers from the 11 Associated Institutions are also part of the Institute, making a total of 63 permanent researchers.
In addition, the INFO has about 150 researchers being trained, among post-docs, doctoral students, master's degree and scientific initiation students (undergrad).
The names and e-mail addresses of the leading researchers and trainee researchers are listed below, remembering that postdocs and students are transient, and the e-mail address may be outdated at some point or the researcher has already completed their formation.
The administrative management of the INFO is carried out by the researchers themselves, with the support of personnel from the coordinating institution (UFPE). INFO has a Steering Committee made up of researchers from the consolidated institutions and the former coordinator of the INFO phase I. The table below shows the administrative structure of INFO.
