Lifetime distribution of spontaneous emission from line antennas in two-dimensional quasi-periodic photonic crystals
JOURNAL OF PHYSICS-CONDENSED MATTER(2008)
摘要
We investigate the lifetime distribution functions of spontaneous emission from line antennas embedded in finite-size two-dimensional 12-fold quasi-periodic photonic crystals. Our calculations indicate that two-dimensional quasi-periodic crystals lead to the coexistence of both accelerated and inhibited decay processes. The decay behaviors of line antennas are drastically changed as the locations of the antennas are varied from the center to the edge in quasi-periodic photonic crystals and the location of transition frequency is varied.
