We demonstrated electrically-driven subwavelength surface plasmonic nano-circuits integrating gap-plasmon emitting nano-LEDs and deep-subwavelength slot waveguides with a cross-sectional area of ∼0.016λ2 for the first time. Owing to the Purcell enhancement within the extremely small, metal-clad active region of the nano-LED, gap-plasmons are extracted efficiently. The gap-plasmons propagating along...
Plasmonics is an exploding new field of science and technology in which the flow of light can be molded at the nanoscale using metallic nanostructures. This newly found ability is rapidly impacting every facet of optics and photonics and is enabling a myriad of exciting new technologies. Group IV photonics has also seen tremendous recent progress in the development of high performance light sources,...
