Brillouin gain curves of a standard optical fibre have been measured down to 3 K. In comparison with their well-documented characteristics at room temperature, they show original and interesting features, namely non-monotonous variations of the central frequency shift and of the linewidth. These preliminary measurements indicate that Brillouin-based temperature sensors can advantageously be used in cryogenics with some adaptations.
