Subwavelength grating (SWG) filters have shown great promise for WDM applications. However, the small feature sizes necessary to implement these structures have prohibited them from penetrating into ...

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 ...
