摘      要：Efficient complementary metal-oxide semiconductor-based nonlinear optical devices in the near-infrared are in strong *** to two-photon absorption in silicon,however,much nonlinear research is shifting towards unconventional photonics *** this work,we demonstrate the generation of an octave-spanning coherent supercontinuum in a silicon waveguide covering the spectral region from the near-to *** input pulses of 18 pJ in energy,the generated signal spans the wavelength range from the edge of the silicon transmission window,approximately 1.06 to beyond 2.4μm,with a−20 dB bandwidth covering 1.124–2.4μ*** octave-spanning supercontinuum was also observed at the energy levels as low as 4 pJ(−35 dB bandwidth).We also measured the coherence over an octave,obtaining|g_()12^(1)(λ)90%,in good agreement with the *** addition,we demonstrate optimization of the third-order dispersion of the waveguide to strengthen the dispersive wave and discuss the advantage of having a soliton at the long wavelength edge of an octave-spanning signal for nonlinear *** research paves the way for applications,such as chip-scale precision spectroscopy,optical coherence tomography,optical frequency metrology,frequency synthesis and wide-band wavelength division multiplexing in the telecom window.
