Abstract
HighlightsLong-range surface plasmons were first excited in a hybrid photonic-crystal/organic-light-emitting-diode microstructure containing two metal nanolayers.These surface plasmons were excited without any external laser light, but by injecting current through the two metal nanolayers, which serve as thin metal electrodes for organic light-emitting microfilm between the layers.
Highlights
The broad interest in the problems associated with surface plasmon (SP) amplification and lasing, witnessed for at least 20 years, has been driven by the practical necessities of the miniaturization of electronic and optical devices: lowering power consumption, increasing the operating frequency range, requiring increasing degrees of integration
Four different independent organic light-emitting diode (OLED) structures with sizes of approximately 4 × 4 mm2 were prepared on each 1D photonic crystal (PC) chip with a diameter of 25.4 mm
The long-range surface plasmons (LRSPs) resonance manifested itself at λ = 575 nm, near the light line, as expected from the structure design
Summary
The broad interest in the problems associated with surface plasmon (SP) amplification and lasing, witnessed for at least 20 years, has been driven by the practical necessities of the miniaturization of electronic and optical devices: lowering power consumption, increasing the operating frequency range, requiring increasing degrees of integration. There is a general belief that optics-based approaches, due to their inherent advantages over electronic ones, will progressively replace the latter. Any surface source of light that can work in the field of future photonics or its interface with electronics must not depend on an external bulk laser (for corresponding operational purposes) providing optical pumping. The generation of surface plasmons propagating exactly along the corresponding interface(s), rather than, for example, lasing in the direction perpendicular to the surface with the nanoplasmonic particles/structures, is needed
