Nonlinear losses of highly nonlinear silicon/organic photonics slot waveguides are analyzed. Unlike silicon strip waveguides, slot waveguides do not show absorption related speed limitations up to highest input powers. Introduction Highly nonlinear waveguides are key components for all-optical on-chip processing at highest bit rates. Of Potential of slot waveguides for silicon-based optical Potential of slot waveguides for silicon-based optical interconnects Yehea Ismail, Hosam Mekawey, Rania Gamal and Mohamed A. Swillam Compact dielectric and plasmonic slot waveguides have low loss characteristics and can be fabricated in a CMOS-compatible manner, and are thus suitable for integration in modern integrated circuits. Silicon-on-Insulator Slot Waveguides: Theory and In fact, slot waveguides have become the key element in order to implement organic materials into silicon photonics. Beside the strip and slot waveguide, the strip-loaded slot waveguide is utilized in this work. The cross section of each waveguide type is shown in Figure 1.
