HIGHLIGHTS
- who: Sareh Vatani from the Modares University have published the research work: All-optical AZO-based modulator topped with Si metasurfaces, in the Journal: Scientific Reports Scientific Reports
- what: The authors demonstrate how the pump fluence affects the mean carrier concentration of the AZO layer, thereby altering the AZO layer`s permittivity through Eqs and_(2).
SUMMARY
The proposed structure. The light employed as the controlling signal in the proposed all-optical modula- tor has photons of energy higher than the bandgap of the active material to excite the valance band . . .
