dc.description.abstract | High modulation speed of light-emitting diodes (LEDs) is of primary importance for applications in optical communication. To this end, we experimentally investigated enhancement behaviors of the spontaneous emission rate (SER) of electronehole pairs in blue InGaN/GaN LEDs by mediating surface plasmons (SPs). The coupling strength of the electronehole recombination into SPs is controlled by etching the p-GaN layer between the active and metal layers to form thicknesses between 40 nm and 10 nm. While a tendency of increasing SER is theoretically expected for a smaller separation, the maximum value SER enhancement has a practical limit of about 2.5 at lambda = 441 nm, and separation of 20 nm due to damage on the p-GaN layer caused by the etching process.
