Gap modes of one-dimensional photonic crystal surface waves
Pile, David F. P. (2005) Gap modes of one-dimensional photonic crystal surface waves. Applied Optics, 44(20), pp. 4398-4401.
The finite-difference time-domain method is employed for the analysis of coupling of the surface modes of two truncated one-dimensional photonic crystals separated by a gap. Wavevector, field distributions and existence conditions of the coupled surface modes are investigated. The wavevector of symmetric gap modes increases with decreasing gap width, while that of antisymmetric modes decreases - exactly opposite to the situation for surface plasmons on metallic half-spaces separated by a dielectric gap. Photonic crystal gap modes could be easily used as effectively non-dissipating gap mode waveguides.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
