Integral temperature hybrid laser sensor

Abstract: An integral temperature sensor based on Brillouin laser ring that is feed by a Fourier Domain mode-locking (FDML) laser is here proposed. The source FDML laser ring emits at 1532 nm within a range of 5 nm. The working wavelength is given by tuning the offset voltage applied to a Fabry-Perot tunable filter (FFP-TF). In the present work, the FDML laser linewidth is set at 0.136 nm. This linewidth allows a more efficient Brillouin response in the optical fiber without increasing the Brillouin threshold. The FDML laser linewidth is controlled by setting the amplitude modulation of the drive signal offset applied on the FFP-TF.
