K. Noda, H. Lee, Y. Mizuno, and K. Nakamura, “First demonstration of Brillouin optical correlation-domain reflectometry based on external modulation scheme“, Jpn. J. Appl. Phys., vol. 58, no. 6, 068004 (2019).

We demonstrate basic operation of Brillouin optical correlation-domain reflectometry (BOCDR) based on external modulation scheme, which can mitigate three demerits of conventional direct modulation scheme. A 0.8-m-long strain in a 2.8-m-long silica fiber is successfully detected in a distributed manner. This scheme can be employed not only in BOCDR but also in Brillouin optical correlation-domain analysis.
