Abstract

We experimentally demonstrate a compact, long-range, high-resolution chaotic correlation optical time-domain reflectometry based on a monolithic integrated chaotic laser (MICL). The MICL can directly generate a broadband chaotic signal covering a RF frequency range of over 40 GHz. Multi-reflection events can be precisely located in a detection range of ∼47 km with a range-independent resolution of 2.6 mm.

摘要

我们通过实验证明了一种基于单片集成混沌激光器（MICL）的紧凑、远程、高分辨率混沌相关光时域反射仪。该单片集成混沌激光器可直接产生覆盖超过40 GHz射频频率范围的宽带混沌信号。在约47 km的探测范围内，多反射事件能够以与距离无关的2.6 mm分辨率精确定位。
