Optimizing performance for an on-chip stimulated Brillouin scattering-based isolator

Yang Liu

Non-reciprocal optical components such as isolators and circulators are crucial for preventing catastrophic back -reflection and controlling optical cross talk in photonic systems. While non-reciprocal devices based on Brillouin intermodal transitions have ...

Spatial Modulation of Vibrational and Luminescence Properties of Monolayer MoS & x2082; Using a GaAs Nanowire Array

Anna Fontcuberta i Morral, Wonjong Kim, Jean-Baptiste Leran, Mirjana Dimitrievska, Lucas Güniat, Didem Dede, Valerio Piazza, Akshay Balgarkashi

The integration of transition-metal dichalcogenides (TMDs) with non-planar substrates such as nanopillars provides a way to spatially modify the optical properties mainly through the localized strain. Similar studies to date have utilized insulating SiO2 n ...

Unusual Shubnikov-de Haas oscillations in BiTeCl

Helmuth Berger, Arnaud Magrez, Philippe Bugnon

We report measurements of Shubnikov-de Haas oscillations in single crystals of BiTeCl at magnetic fields up to 31 T and at temperatures as low as 0.4 K. Two oscillation frequencies were resolved at the lowest temperatures, F-1 = 65 +/- 4 T and F-2 = 156 +/ ...
