Lead-free FASnI3 laser amplifiers integrated in flexible waveguides
(Optica Publishing Group, 2022)
A FASnI3 lead-free perovskite is integrated in a flexible waveguide to demonstrate Amplified Spontaneous Emission. An extremely low threshold, 1 µJ/cm2, is observed together with the formation of narrow random lasing lines ...
Waveguide Amplifiers and Lasers Based on FASnI3 Perovskite Thin Films
(IEEE, 2023-07-02)
In this work, high-quality polycrystalline formamidinium tin iodide (FASnI 3 ) perovskite thin films are integrated into rigid and flexible substrates to demonstrate optical amplification and lasing. With an appropriate ...
