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 CsPbBr3 perovskite
nanocrystals (PNCs). The optimum fabrication conditions were found to enhance the optical gain,
up to +3 dB in the best device. Experimental results were approximately reproduced by a gain
assisted mechanism based on the nonlinear optical properties of the PNCs, indicating that signal
regeneration can be achieved under low pump powers, much below the threshold of stimulated
emission. The results can pave the road for new functionalities of the HC-NCF with PNCs, such as
optical amplification, nonlinear frequency conversion and gas sensors. [-]
