Increasing demand for faster information transport has driven a tremendous progress towards smaller, and faster. Plasmonic interconnects are superior to the electronic ones by virtue of their large operational bandwidth, and huge data transmission capability. An unprecedented synergy could be reached by integrating photonic, plasmonic and electronic devices into the same platform with fully exploiting the advantages of photonics, plasmonics and nanoelectronics technologies.

This presentation will talk the computational electromagnetics methods applied in the nano-photonics devices/circuits simulation and design. Using plasmonic waveguides for on-chip nanoscale optical data transmission is proposed. To optically transmit data between electronic devices, we need to develop a number of plasmonic devices, such as plasmonic sources, modulators, waveguides, switches, filters and detectors. We report a novel planar hybrid plasmonic waveguide (PHPW), which consists of a low-index stripe sandwiched between a high-index nanowire and a metallic film.

Simulation studies show that the optical power can be efficiently coupled from the plasmonic waveguide to the plasmonic detector. The extremely small active area in the detector results sub-picosecond transit-time and atto-Farad internal capacitance, implying a potential THz-bandwidth. In addition, the nanoantenna, nanocavity and detector are integrated seamlessly, leading to an ultra-compact detection structure with high photoresponsivity own to the highly concentrated optical power distribution.
