Surface-relief gratings with high spatial frequency fabricated using direct glass imprinting process

Abstract

Surface-relief gratings with high spatial frequencies were first fabricated using a direct imprinting process with a glassy carbon mold at the softening temperature of phosphate glass. A grating with maximum height of $730\mathrm{nm}$ and $500\mathrm{nm}$ period was formed on the glass surface by the pressing at the softening temperature of glass under constant pressure of $0.4\mathrm{kN}∕{\mathrm{cm}}^2$. Phase retardation of $0.1\lambda$ was observed between TE-polarized and TM-polarized light at $600\mathrm{nm}$ wavelength.
