Silver nanoparticles grown in nanochannels of anodic aluminum oxide on a grating form a surface-enhanced Raman scattering (SERS) substrate with the double resonance from both localized and delocalized ...

Abstract: We demonstrate a grating coupler with reduced back reflection on silicon-on-insulator (SOI) platform. Each grating tooth of the grating coupler is uniformly divided into multiple sub-teeth ...
