As I began to write this editorial, I was reflecting on 2015 and the technological advancement and innovation we’ve seen industrywide. However, my thoughts quickly turned to our founder, Teddi Laurin, as we said goodbye to her on Nov. 5. She is widely credited with establishing the term “photonics” into popular and global use during her expansive career that began in the early 1960s, when she collaborated with Eastman Kodak optical scientist Dr. Clifton M. Tuttle to produce an annual optical industry directory; now the Photonics Buyers’ Guide, it remains one of the most commonly used industry resources more than 60 years later. In 1967, Teddi saw “a need to put under one tent the ever-widening range of subdisciplines that optics had spawned,” which led her to establish Optical Spectra (now Photonics Spectra); it quickly emerged as the industry’s leading trade magazine, and remains so today. Teddi made a name for herself in science and journalism during a time when few women were in leadership positions in publishing and photonics. For these reasons and more, we feel a strong drive to continue her mission to serve this industry. Soon we will dim the lights on 2015, and the worldwide International Year of Light (IYL) celebration, which certainly will have a lasting impact on the photonics industry, and the world. In this issue, we revisit some of the top stories of 2015 — from the many IYL activities and celebrations held all over the world, to innovative research and business news impacting the industry. After first appearing on Photonics.com, many are later featured in the pages of EuroPhotonics. Read more beginning on page 22. Also in this issue: • Frank Gäbler, of Coherent Inc., explains the advantages high-power diode laser cladding has over traditional laser sources. Page 30. • Robert Hartley, of CoolLED Ltd., discusses the increasing benefits LEDs are demonstrating in microscopy, optogenetics and other biology research. Page 26. • We explore the photonics industry’s growing presence in Eastern Europe, and how countries there are accelerating education and training for students, researchers and other industry players.
