Impact of pump depletion on the determination of the Brillouin gain frequency in distributed fiber sensors

Luc Thévenaz, Stella Foaleng Mafang, Jie Lin

The energy transfer between the two interacting optical waves in a distributed sensor based on stimulated Brillouin scattering can lead to a non-uniform spectral distribution of the pumping power after a long propagation. This results in a spectrally disto ...

Visibility of dichalcogenide nanolayers

Andras Kis, Helmuth Berger, Branimir Radisavljevic, Mohamed Malik Benameur

Dichalcogenides with the common formula MX2 are layered materials with electrical properties that range from semiconducting to superconducting. Here, we describe optimal imaging conditions for the optical detection of ultrathin, two-dimensional dichalcogen ...
