Electronics Letters, Volume 57, Issue 3, Page 142-144, February 2021., 2021 Abstract Brillouin optical time‐domain reflectometry (BOTDR) has the advantage of requiring access to only one end of the sensing fibre, which is an important property for some applications. The coherent detection of spontaneous Brillouin scattering allows high sensitivity of temperature/strain measurements, close to one of the well‐known Brillouin ...

Universal Method for Constructing Fault‐Tolerant Optical Routers Using RRW
Wireless Communications and Mobile Computing, Volume 2021, Issue 1, 2021., 2021 High‐speed data transmission enabled by photonic network‐on‐chip (PNoC) has been regarded as a significant technology to overcome the power and bandwidth constraints of electrical network‐on‐Chip (ENoC). This has given rise to an exciting new research area, which has piqued the public’s attention.
