Abstract :
We present ultrahigh-speed transmission of 3.84-Tbit/s 64-QAM signal in Si ridge and Si slot waveguides. Si slot waveguide confining light in air slot region features reduced nonlinearity and resultant superior transmission performance with low penalty for varied input signal power from 1 to 250 mW.
