The study of light and light-based technological advancement is becoming an economic and social need in the 21st century, and hence photonics is essential to our everyday lives to provide solutions to global challenges in energy, education, agriculture, health, communication, information processing, etc. It goes without saying that photonics has now influenced a wide range of scientific and technological fields, becoming a significant and rapidly evolving area of growing multidisciplinary interest. Medical diagnostics, organic synthesis, communications, and fusion energy are just a few of the many scientific and technical uses for photonics. This can improve people’s quality of life across various industries, including advanced manufacturing, military, healthcare, and energy. Today, photonics is also widely employed in agriculture. Without sensors and cameras on tractors and drones, it would be difficult to analyze soil and crops and identify areas that need fertilizer application in precision agriculture. Photonics is also used to predict when and how to harvest crops.
