Optical Science and Photonics in Africa: introduction

Optical science and photonics are driving the world’s advancement of knowledge and economy, encompassing important areas such as green photonics, bio-photonics, agro-photonics, environmental photonics, and so on. These areas are at the heart of the needed development for the African continent. This feature issue will discuss some of the works being conducted in these areas in African photonics research laboratories and will inform researchers in Africa of the current works in optics and photonics taking place. The special issue will not only cover research advances but also will present a perspective on challenges and opportunities, including impact on society, through studies that address continental issues, highlighting the excellence in optical science and photonics research presently underway in Africa. With its emerging excellence, it is high time to showcase optics by Africans to Africans, and to the world.
