摘要:

介绍了一种基于周期极化铌酸锂(PPLN)波导的单像素上转换红外光谱仪。1.5微米波段的扫描泵浦激光和1.3微米波段的信号之间的和频产生的可见光辐射,这是由硅单光子探测器检测。上转换光谱仪的噪声等效功率比商用光谱分析仪低两个数量级。

英文摘要:

A periodically poled lithium niobate (PPLN) waveguide-based single-pixel up-conversion infrared spectrometer was demonstrated. Sum-frequency generation between a 1.5 micrometer band scanning pump laser and a 1.3 micrometer band signal generated visible radiation which was detected by a silicon single-photon detector. The noise equivalent power of the upconversion spectrometer was two-orders-of-magnitude lower than that of a commercial optical spectrum analyzer.
