Diffraction resonance with strong optical-field enhancement from gain-assisted hybrid plasmonic structure

Diffraction resonance with strong optical-field enhancement from gain-assisted hybrid plasmonic structure

We propose and analyze the diffraction coupling of localized plasmon resonances (LPRs) through gain-assisted propagation surface plasmons (PSPs). The coupling process involves localization of incident light by LPR and LPR-PSP interaction. We demonstrate a significantly strong enhancement of electrom...
