Reconfigurable group delay with tunable topological edge state based on phase transitions material Ge2Sb2Te5 in dual-band
We investigate reconfigurable reflected group delay in dual-band of the photonic crystal heterostructure containing phase transitions material Ge2Sb2Te5 and graphene in mid-infrared region. The giant phase change of reflected beam derives from the topological edge state excited at the boundary surfa...
