Antimonene-based all-optical modulator

15 марта, 2019 - 08:10
In recent years, all-optical modulators (AOMs) have attracted significant interests due to their low power consumption, broad bandwidth, and potential in all-optical fields. Among these, AOMs based on the high photothermal efficiency of antimonene, exhibit remarkable advantages for their large modulation depth, wide operating wavelength range, and easy implementation. Researchers demonstrated that an antimonene-based AOM was successfully utilized to actively Q-switch a fiber laser in a fully photonics domain and this actively modulated laser represented all-optically tunable output parameters, and easy time synchronization.
