title = "Impact of non-Lorentzian laser phase noise on ϕ-OTDR performance",
abstract = "We highlight the importance of the laser source phase noise in sensing applications and show that the standard Lorentzian linewidth criterion is not sufficient to characterize the performance of a sensing system. We then derive a laser linewidth related to the phase noise spectral region of interest, according to the length of the fiber to sense. This is illustrated in a setup based on coded interrogation and with two sensing dedicated laser sources.",
