Schematic and theoretical results of strong-confinement rib-loaded waveguide

Caption

Fig. 1 Schematic and theoretical results of strong-confinement rib-loaded waveguide. (a) Schematic of strong-confinement rib-loaded waveguide with electrodes. The inset shows the cross-section view of the structure. (b) neff1 and neff2 as functions of different nrib. (c) Dispersion relationships of different regions of the structure in the inset of (a). The orange region represents the guided mode while the blue region represents the leaky mode. (d) p and penetration depth as functions of nrib. (e) Relationship between power confinement ratio and hrib for various nrib. (f) Relationship between propagation loss and hrib for various nrib with electrodes added.
