We demonstrate low-loss slot waveguides on silicon-on-insulator (SOI) platform. Waveguides oriented along the (11-2) direction on the Si (110) plane were first fabricated by a standard e-beam lithography and dry etching process. A TMAH based anisotropic wet etching technique was then used to remove any residual side wall roughness. Using this fabrication technique propagation loss as low as 3 ...
2. Highly Nonlinear SOI Slot Waveguides and Optimization for Maximum Nonlinearity The structure of the highly nonlinear silicon on insulator slot waveguide is shown in Fig. 1(a). Its core consists of two silicon (Si) ribs on a silicon buffer (SiO2). The slot waveguide is filled and covered with a Kerr-type nonlinear organig cladding (NL).
