我们在 1.54 μm 波长下测量硅波导中的线性光学色散、非线性折射和双光子吸收。发现硅波导中的总色散为-9.1 fs/(nm cm)。在 1.54 μm 波长处，双光子吸收系数为 0.45 cm/GW，并且在由放大增益开关激光二极管产生的 60 W 峰值耦合功率的光脉冲中观察到自相位调制的 pi 相移。 (C) 2002 年美国物理研究所。
We measure linear optical dispersion, nonlinear refraction and two-photon absorption in a silicon waveguide at 1.54 mum wavelength. The total dispersion in the silicon waveguide was found to be -9.1 fs/(nm cm). At 1.54 mum wavelength, the two-photon absorption coefficient was found to be 0.45 cm/GW and a pi phase shift from self-phase modulation was observed in optical pulses of 60 W peak-coupled power, generated from an amplified gain-switched laser diode.
