2022 IDL Campaign

Our future is light. Play your part. Woman stands facing sunset at the beach

An action-packed video styled as a blockbuster-movie trailer provides the linchpin for this year's International Day of Light (IDL) campaign, "Our future is light. Play your Part." Released on 16 May, 2022, Day of Light features diverse characters successfully solving global-level problems using photonics-enabled tehcnologies.

We partnered with IEEE Photonics Society and Optica, to create the video and an accompanying website to promote the importance of light-based technologies and interesting careers in optics and photonics, while raising awareness of the annual IDL celebration on 16 May. From technolgies that improve vision and power smartphones, to those that provide tools to study Earth and Space, from healthcare to communication at the speed of light, photonics is the key enabling technology of a brighter future. Read the SPIE news article to learn more about the campaign.
