Key challenge in the design of plasmonic nano-waveguide is to simultaneously achieve high confinement and low propagation loss. This paper presents that a planar hybrid dielectric-loaded plasmonic nano-waveguide (HDLW) could be a promising candidate to build high-performance plasmonic components. Our studies show that the HDLW can achieve better trade-off between the field intensity confinement and...
The high speed of optical devices motivates the integration between electronics and photonics. One of the most common optoelectronic devices used for such integration is a photodetector. This paper describes the formulation of an optical absorption inside a photodetector using the non-equilibrium Green's function (NEGF) framework. To illustrate the use of the formulation, optical properties of a double...
