This study reports our numerical simulation of light extraction efficiency enhancement for a single quantum well by Extraordinary Optical Transmission (EOT) induced by a silver plate with air slit array. Our numerical experiment indicates that the enhancing effect could depend on a series of factors, namely, the nature of EOT, the polarizations and the positions of the quantum wells. Only by using TM polarized source significant enhancement can be achieved, and the enhancement excited by Fabry-Perot resonance is greater than that by surface plasmon polaritons; yet moving the source off the Ag/GaN interface will have the enhancement weakened. Position of the source, to be specific, either below an air slit or a silver strip, can lead to quite different results; and the greatest enhancement occurs when the source is placed right below the air slit.
