摘要：
A light-emitting diode (LED) (101). The LED (101) includes a plurality of portions including a p-doped portion (112), an intrinsic portion (114), and a n-doped portion (116). The intrinsic portion (114) is disposed between the p-doped portion (112) and the n-doped portion (116) and forms a p-i junction (130) and an i-n junction (134) The LED (101) also includes a metal-dielectric-metal (MDM) structure (104) including a first metal layer (140), a second metal layer (144), and a dielectric medium disposed between the first metal layer (140) and the second metal layer (144). The metal layers of the MDM structure (104) are disposed about orthogonally to the p-i junction (130) and the i-n junction (134); the dielectric medium includes the intrinsic portion (114); and, the MDM structure (104) is configured to enhance modulation frequency of the LED (101) through interaction with surface plasmons that are present in the metal layers.
