摘要
We experimentally investigate four-wave mixing and non-linear losses in low-loss 3 mu m thick silicon strip waveguides. Adiabatic bends allow for single-mode operation in an ultra-compact 35 cm long spiral. The waveguides exhibited reduced nonlinear losses due to the large mode area of 2.75 mu m(2). The nonlinear coefficient gamma was measured as 5.5 m(-1) W-1. These features, along with the low propagation loss of 0.17 dB/cm, enable large idler power generation at 1550 nm.
