Abstract
We report a significant increase in electroluminescence from GaSb based mid-wave infrared inter band cascade (IC) LED device through coupling with localized surface plasmon layer. Thin Au Plasmon layer of 20 nm thickness is deposited on top anode electrode by e-beam evaporation technique. Surface Plasmon enhancement effects result is 100% increase in light output for 50 μm square mesa device. We fabricated an IC LED device with nine cascade active/injection layers with InAs/Ga1-xInxSb/InAs quantum well (QW) active region.
