Optical Amplification in Hollow-Core Negative-Curvature Fibers Doped with Perovskite CsPbBr<sub>3</sub> Nanocrystals

Optical Amplification in Hollow-Core Negative-Curvature Fibers Doped with Perovskite CsPbBr<sub>3</sub> Nanocrystals

We report a hollow-core negative-curvature fiber (HC-NCF) optical signal amplifier fabricated by the filling of the air microchannels of the fiber with all-inorganic CsPbBr<sub>3</sub> perovskite nanocrystals (PNCs). The optimum fabrication conditions were found to enhance the optical ga...
