Asymmetric slot waveguides definition

24 Sep 2018 Our asymmetric strip-loaded slot waveguide design is similar to that of a .. Another advantage of the metal-defined optical waveguide 1. With this definition, symmetric slot waveguides have an asymmetry degree equal to zero. (a) Symmetric slot and (b) asymmetric slot silicon-on-insulator slot fill factor, i.e., the ratio between the slot and waveguide widths, is analyzed. The fill factor is defined as the normalized ratio between the slot and the waveguide widths. Chromatic dispersion is defined as variations in the refractive index of a medium as a .. symmetrical and asymmetrical vertical slot waveguides, depending on. We then show that for an asymmetric plasmonic slot waveguide, in which the . eigenvalue equations allows one to define the propagation length Lp and theAbstract: We demonstrate low-loss asymmetric slot waveguides in silicon- on-insulator (SOI). An asymmetric waveguide design is shown to expand the range in which the TE0 mode is guided and suppress the TE1 mode, while still maintaining a sharp concentration of electric field in the center of the slot. air-SiO2 asymmetric waveguide supports leaky modes above the cutoff slot width or film . Subsequently, the plasmonic slot waveguide was defined by We demonstrate low-loss slot waveguides on silicon-on-insulator (SOI) platform. confinement in the slot region due the asymmetry in the waveguide geometry. . The waveguides were first defined during the dry etching process and then Slot-waveguide. From Wikipedia, the free encyclopedia. A slot-waveguide is an optical waveguide that guides strongly confined light in a subwavelength-scale low refractive index region by total internal reflection.
