Light based technologies have the potential to transform the 21st
Century as electronics did in the 20th Century according to the UN
cultural agency (UNESCO).
2015 has been designated by the United Nations as the International Year of Light and Light-based Technologies (IYL).
The Year will kick off with opening ceremonies to be held at the UNESCO headquarters in Paris on 19 and 20 January.
A global campaign will be launched called "1001 Inventions and the World of Ibn Al Haytham".
Ibn Al-Haytham, who is often referred to as the "father of modern
optics" is an Arab scientist and philosopher from Basra in modern day
Iraq who lived in the 10th century.
He made significant advancements in optics, mathematics and
astronomy, and helped lay the foundations of modern scientific method.
According to UNESCO, light-based technologies can provide solutions
to global challenges in energy, education, agriculture and health.

In fact, according to UNESCO, photonic technologies, which already make vital contributions towards energy generation and energy efficiency, have a “major impact” on the world economy with a current global market of almost $350 billion and a projected market value of over $700 billion in 2020.
