Welcome to SIFA

Formerly known as the Photonics Research Group, SIFA is now proudly part of the Federal University of Sergipe. Our mission is to advance the science of light and its interaction with matter, developing innovative photonic materials and sensor devices. We specialize in areas such as linear and nonlinear spectroscopy, random lasers, and the application of photonics in agribusiness and ionizing radiation through light sensing technologies. Our collaborative approach bridges academia and industry, fostering unique solutions to real-world challenges. Explore our research, meet our team, and discover how we are shaping the future of photonics.

Joint Research Project
in
AgriPhotonics
(Binding Industry & Academia)

Agriphotonics has already drastically improved precision agriculture. However, conventional sensors are still used for their performance and low cost. Replacing conventional sensors with photonic ones requires a better understanding of acquiring physical parameters in the real world (off-lab). Therefore, we have developed a low-cost DAQ system using conventional sensors to measure physical parameters in the subsoil of sugar cane crops. The main goal is to substitute traditional sensors with photonic devices or techniques to obtain the same information. Finally, this joint research project is a perfect example of how to bind industry and academia.

Controlling Whitefly Pest With Laser

Whitefly Bemisia tabaci is among the most important agricultural pests in the world and one of the world’s top 10 most invasive insect pests. We have published a paper proposing a solution to control this pest using a laser — the first successful case of our collaboration with EMBRAPA.
