Here, we used the micro P-scan method to investigate the saturated absorption (SA) of
different layered Bi_2Se_3 continuous films. Through resonance excitation, first, we studied …

An all-optical light–control–light functionality with the structure of a microfiber knot resonator
(MKR) coated with tin disulfide (SnS_2) nanosheets is experimentally demonstrated. The …

Antimonene has been found to possess excellent nonlinear refractive and saturable
absorption properties recently. To further investigate its optical limiting properties, we …
