Mico-photoluminescence of surface plasmon enhanced emissions from semi-polar InGaN/GaN quantum wells

We have reported that enhancement of blue/green emission by SP resonance of InGaN/GaN quantum wells (QWs) on the polar-GaN substrate. In this study, we investigate SP enhanced light emissions also for InGaN/GaN QWs on semi-polar GaN substrate, where further enhancements can be expected.
