摘要: Abstract Electro-optic glass for light modulators Light are important processing of optical signals. allow to control and influence the phase, frequency, amplitude, or polarization passing beam. Optical materials with a sufficiently high electro-optic coefficient needed construction efficient fast operating in VIS NIR regions. Heavy-metal oxide glasses based on PbO-Bi2O3-Ga2O3 system represent highest non-linear susceptibility among materials. Glass samples those addition Ag2O Sb2O3 were prepared by melt quenching. Thermal properties investigated using differential thermal analysis. studied spectroscopy UV-VIS-IR region spectrum. The transparent from 550 nm up 7.4 μm. maximum refractive index determined M-line was found at 473 nm is equal 2.49. calculated rotation angle polarized through sample which voltage 5 30 kV applied. obtained values these construct intensity phase effect.
