METHOD OF OBTAINING POLARIZATION CONVERTER Russian patent published in 2018 - IPC G02B5/30 C03C3/91 C03C3/87

Abstract RU 2640603 C1

FIELD: physics.

SUBSTANCE: oxide glass is treated with a focused laser beam. The glass melting is performed at temperatures from 1650 to 1700°C. The composition of the glass is as follows, in mol. %: MgO 5-10, CaO 5-10, B₂O₃ 5-10, Al₂O₃ 15-20, SiO₂ 55-65.

EFFECT: simplification of the technology, reduction of the standard deviation of the value of the phase shift of the nanogrid.
