An efficient orthogonal coupler for silicon photonics with the degenerate plasmonic modes
{{output}}
An orthogonal coupling structure is proposed to collect the near-infrared lightwaves into a SiO2/Si/SiO2slab waveguide, which is mainly based on the generation of degenerate plasmonic longitudinal modes in an Ag/SiO2/Ag V groove. The coupling efficiency of the... ...
