Popis: By applying pulsed laser and CW laser to irradiate the top layer phase-change material GST, we realized reversible optical switching of reflectance of a layered structure. The FTIR measured reflectance spectrum proved that the reflectivity at 8 μm could be changed reversibly from 0.19 to 0.90. Our research may have some inspiration for active thermal control and other applications.
