Celebrating International Day of Light 2022

The International Day of Light is a global initiative that provides an annual focal point for the continued appreciation of light and the role it plays in science, culture and art, education, and sustainable development, and in fields as diverse as medicine, communications, and energy. The broad theme of light will allow many different sectors of society worldwide to participate in activities that demonstrates how science, technology, art and culture can help achieve the goals of UNESCO – education, equality, and peace.

May 16 is the anniversary of the first successful operation of the laser in 1960 by physicist and engineer, Theodore Maiman. The laser is a perfect example of how a scientific discovery can yield revolutionary benefits to society in communications, healthcare and many other fields.

In honor of the International Day of Light, Editor-in-Chief Professor Romain Quidant (ETH Zürich) has selected outstanding contributions in quantum photonics, biophotonics, nanophotonics, imaging, devices and energy, published in ACS Photonics.

About the Journal

ACS Photonics is an interdisciplinary forum to communicate on the latest advances in the field of photonics, all the way from basic research to applied research and technology. Embracing the transversality of photonics, it connects scientists and technologists from a broad scientific spectrum, at the interface between physics, chemistry, biology, and engineering. It also aims at bridging the gap between the academic and industrial worlds.
