Globalization in Photonics

On behalf of the Guest Editors, I am delighted to present this special issue of the IEEE Photonics Journal, focusing on Globalization in Photonics.
This all-invited issue collects several detailed overviews of world-wide developments in photonics, based on a series of presentations that were previously shared in a dedicated symposium at the IEEE Photonics Conference, in November 2023, in Vancouver, Canada.
Photonics is a global field, in which highly interconnected multinational and multicultural technical teams work together to address challenges in engineering and research. Rapid growth, new discoveries and novel applications with high societal impact are emerging across the globe, with much exciting progress in photonics taking place in regions outside of the highly industrialized countries. Additionally, there is a large global cadre of students that are eager to be the next generation of photonics engineers and scientists and who are willing to contribute to the growth of photonics.
We highlight in this special issue some of the excellent work and advances in photonics which are taking place world-wide. The papers also emphasize how the photonics field in general and the engineers and scientists in both emerging and more established regions can benefit from closer cooperation, exchanges and partnerships.
The invited papers included in this special issue present an overview of photonics developments for specific global regions. As appropriate, progress in the field is illustrated with selected examples from the Authors’ own work.
We thank the Authors for their willingness to review the state of photonics for their respective regions in support of this publication. We are also sincerely grateful to the IEEE editorial staff for their commitment and hard work in making possible this IEEE Photonics Journal special issue.

Progress in Semiconductor Lasers

On behalf of the editors, I am delighted to present this special edition of the IEEE Photonics Journal, focusing on Progress in Semiconductor Lasers.

This feature section includes expanded versions of many of the fine papers that were previously presented at the 27th International Semiconductor Laser Conference, in Potsdam, Germany in 2021.

Selected original manuscripts on the topic of semiconductor lasers that were not presented at the ISLC have also been included.

Overall, the very broad range of topics in the science and technology of semiconductor lasers addressed by the ISLC community is well represented in this special edition. Specifically, the accepted papers include excellent examples of progress in high-power and high-brightness lasers, communications lasers and integrated semiconductor photonics, optical amplifiers, silicon compatible lasers, VCSELs, photonic crystal and nanocavity lasers, grating controlled lasers, quantum cascade lasers, mid IR sources, InP, GaAs and Sb-based materials, quantum dot lasers and GaN-based lasers.

We thank the authors for their support of this special issue, and the guest editors and the IEEE team for their hard work in making this special issue possible.
