Paper Abstract

The emission of erbium ions in silicon at 1550nm is enhanced by the presence of the two-dimensional (2D) plasmonic crystal. The nonradiative surface plasmon polaritons (SPPs) are generated through the relaxation of the excited erbium ions. The SPPs can be highly confined at the edge of the band of the 2D plasmonic crystal. By adding or reducing a multiple of external wave vector, the large amount of SPPs will be coupled out. The emission efficiency of erbium ions with help of reradiated SPPs can increase nearly 40 times comparing to that of one-dimensional (1D) metal grating. The emission angles of enhanced spectrum are discussed.
