a Sketch of the GCG nanowire. The nanowire described in a cylindrical coordinate system is shown in the top inset and its cross-section is shown in the bottom one. Switching “on” (top panel) and “off” (bottom panel) b non-chiral SPP modes at EF = 0.46 eV and c chiral SPP modes at EF = 0.6 eV by changing the GST phase from amorphous to crystalline. Fig. 1b,c share the same color bar. d Comparison of β2 for the EH±1 and TM SPP modes in the GCG nanowire with the crystalline GST core
