SPIE uses a seven-digit CID article numbering system structured as follows:
AuthorsNumbers in the index correspond to the last two digits of the seven-digit citation identifier (CID) article numbering system used in Proceedings of SPIE. The first five digits reflect the volume number. Base 36 numbering is employed for the last two digits and indicates the order of articles within the volume. Numbers start with 00, 01, 02, 03, 04, 05, 06, 07, 08, 09, 0A, 0B…0Z, followed by 10-1Z, 20-2Z, etc. Adles, Eric, 18 Aiko, K., 21 Akahane, Kouichi, 15 Alghannam, Fahad, 0Z Alves, Fabio, 11 Amico, G., 0G Auguste, D., 0G Aumont, J., 0G Ayotte, S., 1A Babin, A., 1A Baili, Ghaya, 1V Balasubramanian, Krishnan, 0D Banfi, S., 0G Barbarán, G., 0G Barnes, Crispin H.

As with prior Terahertz Technology and Applications conferences, these papers represent a cross section of much of the research work that is being pursued in the technically challenging terahertz spectral and other electromagnetic regions. In the prior 11 years of the Proceedings of this conference (SPIE Volumes 6472, 6893, 7215, 7601, 7938, 8621, 8624, 8985, 9362, 9747 and 10103, respectively), we (including Dr. Kurt Linden) presented a list of recent technical articles describing significant advances in the terahertz technology. This year, for the interested reader, we also include a list that points to a rather extensive and growing database on the terahertz absorption characteristics of a large number of chemicals given on the website www.thzdb.org. That website, in turn, provides links to related terahertz technology database websites as shown in Table 1. Table 1.List of terahertz technology database websites as found at www.thzdb.org
In the last 10 years, the introductions to Proceedings of SPIE volumes 6472, 6893, 7215, 7601, 7938, 8621, 8624, 8985, 9362, 9747 and 10103, respectively, included two tables, one summarizing the more common terahertz radiation sources, and the other summarizing the more common terahertz detector types. For the interest of the general reader, we again include these tables without updates, other than to note that recent advancements in vacuum electronics BWOs coupled with solid state multipliers have now produced usable power above 2 THz and that devices such as quantum cascade lasers continue to make improvements that encroach upon established high power sources such as carbon dioxide lasers. Due to such advancements, any values listed in Tables 2 and 3 are likely to be bested by new records in a very short time period; however, the sources and detectors listed in Tables 2 and 3 still comprise the majority of those used in the THz regime. Readers of this volume may send additions and enhancements to these tables so that future volumes can continue to provide readers with relevant information on the availability of terahertz sources and detectors. Such suggestions can be sent to sadwick@innosystech.com. Table 2.Summary of common terahertz sources Table 3.Summary of common terahertz radiation detectors We would like to thank the conference program committee: René Beigang; Jianji Dong; Frank Ellrich, Fabian Friederich, Robert H. Giles, R. Jennifer Hwu, J. Anthony Murphy, Créidhe O’Sullivan, Kyung Hyun Park, Alessia Portieri, Jinghua Teng, Michael Weibel and Jiangfeng Zhou for their great and very much appreciated work on the conference. Finally, we would also like to thank the dedicated staff of SPIE. Laurence P. Sadwick Tianxin Yang |
