Switching platform for writing/erasing laser-induced periodic surface structures (LIPSS) on GST

A switching platform that provides writing and erasing of extended two-phase periodic laser-induced surface structures on the GST has been developed: writing is carried out by fs laser pulses, and erasing - by electric current ones. The obtained results demonstrated the possibility of using a thin-film resistive heating element of the developed design to create elements of non-volatile active integrated optical and optoelectronic devices, for example, tunable diffraction gratings.
