Design and characterization of Silicon On Insulator (SOI) based rib waveguides operating at 1550 nm for single mode transmission in integrated nanophotonics

In this paper, the characterization of single mode Silicon On Insulator (SOI) rib waveguides operating at 1550 nm wavelength is presented for three separate cases. The mode profile of the output is observed when two waveguides are joined together with the presence of a taper or a gap. The designed waveguides are analyzed at different geometrical conditions and then the results are used to design a splitter. The results of the splitter design are used to explore the boundary conditions for single mode operation.
