Ion beam synthesis of nanothermochromic diffraction gratings with giant switching contrast at telecom wavelengths

Johannes Zimmer, Achim Wixforth, Helmut Karl +1

Nanothermochromic diffraction gratings based on the metal-insulator transition of $\mathrm{V}{\mathrm{O}}_2$ are fabricated by site-selective ion beam implantation in a $\mathrm{Si}{\mathrm{O}}_2$ matri…
