A plasmonic waveguide consisting of a graphene monolayer placed above a highindex dielectric wedge is shown to support strongly confined plasmonic modes with low loss, which outperforms the conventional graphene ribbon waveguides.
A novel type of plasmonic nanolaser based on coupled nanowires consisting of a gain material and a core/shell metal/dielectric nanowire is proposed. It shows the potential to enable deep-subwavelength lasing with low pump thresholds.
For equipment is the executive object of production task, to realize the great transformation from “scale production capability” to “innovation ability and rapid response ability”, it has been great demand for enterprises to improve equipment flexible manufacturing capability. by extracting its manufacturing feature, the information model on manufacturing feature is built. Based on the model, the...
Slot waveguide structure gained attention due to high confinement of power inside low index slot region. The high e-field confinement is dependent upon various geometrical parameters. A double slot structure where two low index slots of hard material in high index cladding of compressible material is proposed. Power confinement factor dependency upon distance between low index slots has been numerically...
Since the advent of slot optical waveguides by Lipson, normally SOI based slot optical waveguides have been under consideration. It has been found that glass based slot optical waveguide structures, where refractive index contrast ratio is comparatively less can also play important role in forming complex nano size optical devices. We have made use of power confined inside low index slot region for...
