We demonstrate supercontinuum generation over an octave spaning from 1055 to 2155 nm on the highly nonlinear aluminum gallium arsenide (AlGaAs)-on-insulator platform. This is enabled by the generation of two dispersive waves in a 3-mm-long dispersion-engineered nano-waveguide. The waveguide is pumped at telecom wavelengths (1555 nm) with 3.6 pJ femtosecond pulses. We experimentally validate the coherence of the generated supercontinuum around the pump wavelength (1450-1750 nm), and our numerical simulation shows a high degree of coherence over the full spectrum.
我们展示了在绝缘体上高非线性砷化铝镓（AlGaAs）平台上产生的倍频程超连续谱，其波长范围从1055纳米至2155纳米。这是通过在一个3毫米长的色散工程纳米波导中产生两个色散波来实现的。该波导由电信波长（1555纳米）的3.6皮焦飞秒脉冲泵浦。我们通过实验验证了在泵浦波长（1450 - 1750纳米）附近产生的超连续谱的相干性，并且我们的数值模拟表明在整个光谱范围内具有高度的相干性。
