我们报告了一种新的实验外差技术，用于连续光波源的光谱分析。所实现的分辨率低至千赫兹级，动态范围超过 90 dB。该技术基于被测源 (SUT) 和该 SUT 生成的布里渊光纤激光器之间的外差检测。与标准自外差技术相反，仅需要几十米的光纤，而不需要任何光调制器。该光谱仪已用于表征分布式反馈激光二极管和布里渊光纤激光器。
We report what we believe to be a novel experimental heterodyne technique for the spectral analysis of continuous optical wave sources. The achieved resolution is as low as the kilohertz level, with a dynamic range in excess of 90 dB. The technique is based on a heterodyne detection between the source under test (SUT) and a Brillouin fiber laser generated by this SUT. Contrary to standard self-heterodyne techniques only a few tens of meters of optical fiber is required without the need of any optical modulators. This spectrometer has been used to characterize a distributed-feedback laser diode and a Brillouin fiber laser.
