Because of the relatively higher loss and in-plane radiation of the SPP modes, the LSP modes dominate the enhancement effect. However, because the LSP resonance energy is sensitive to the metal/dielectric interface geometry, it may be difficult to precisely implement a particular geometry and achieve the emission enhancement of a desired emission wavelength based on the LSP coupling. On the other hand, because the SPP feature can be controlled by the period of a grating structure, the implementation of the SPP coupling for emission enhancement in a practical device can be more feasible. © 2008 American Institute of Physics.Dielectric materials; Field emission; Radiation effects; Localized surface plasmon (LSP); Metal gratings; Surface plasmon polariton (SPP) couplings; Surface plasmon resonancejournal article10.1063/1.29063632-s2.0-41649086935WOS:000254669900083
