Abstract :
Glass imprint process was developed for the fabrication of micro- and nano-structures on the surface of glasses. A spherical glass lens with two dimensional subwavelength structure exhibited the surface reflectance less than 0.2% at 530 nm in wavelength. Application of DC voltage to the mold, on the other hand, was effective to suppress the imprint temperature and pressure, which was resulted from the selective decrease in alkali concentration only in the glass surface areas contacting to the mold.
