Long-range and high-resolution correlation optical time-domain reflectometry using a monolithic integrated broadband chaotic laser.
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.
