我们展示了如何在一个埋硫族化物中红外波导的非线性光谱展宽可以用来重塑在4260 nm的飞秒脉冲序列的光谱，以减少由于二氧化碳的大气吸收的影响。非线性光谱展宽导致源的−20 dB光谱宽度跨越3500 nm，从1700 nm到5200 nm。这代表了一个潜在的路线，以定制源的远程中红外应用。
We show how nonlinear spectral broadening in a buried chalcogenide mid-infrared waveguide can be used to reshape the spectrum of a femtosecond pulse train at 4260 nm in order to reduce the effects of atmospheric absorption due to carbon dioxide. The nonlinear spectral broadening results in the source with −20 dB spectral width spanning over 3500 nm, from 1700 nm to 5200 nm. This represents a potential route to tailored sources for long-range mid-infrared applications.
