Keywords:quantum cascade lasers? Optical Engineering?

The accelerated pace of development of quantum cascade laser (QCL) technology is the subject of a highly anticipated special section just published in the international society for optics and photonics journal (SPIE journal), Optical Engineering, having U.S. Naval Research Laboratory scientists Jerry Meyer and Igor Vurgaftmanare as section editors. Such mentioned technology may be utilized in a number of varied applications -- like in monitoring for explosive chemicals on clothing, studying greenhouse gases, measuring blood sugar levels via breath analysis, and more.

Jerry Meyer cites, "In the past 16 years, the QCL has evolved from a barely functional scientific curiosity into a powerful technology poised to offer new capabilities to a broad spectrum of real-world applications." He continues by stating, "Compact and inexpensive semiconductor lasers emitting at wavelengths beyond 3 microns are finally becoming practical and available for the military, research and the commercial marketplace."

The leader of the group that initially demonstrated QCL technology 16 years ago at Bell Labs, Federico Capasso, who is also a professor and senior research fellow at Harvard University contributed an invited review paper entitled "High-performance mid-infrared quantum cascade lasers". His paper is available for free in the 26-article section, as well as through the open-access journal SPIE Reviews.

Other noteworthy section authors include: Kumar Patel, Pranalytica and University of California, Los Angeles; Manijeh Razeghi, Northwestern University; Joachim Wagner, Fraunhofer Institute for Applied Solid State Physics; and other leading international researchers.

Optical Engineering is published in the SPIE Digital Library, with freely searchable abstracts; articles are available via subscription or pay-per-view. Ronald Driggers, Naval Research Laboratory, is Editor-in-Chief. The SPIE Digital Library contains over 300,000 articles from SPIE Journals and Proceedings, with about 18,000 new research papers added yearly.
