Near-infrared polarized glass is widely used in optical communication, optical modulator and laser industry because of its excellent polarization performance, high transmittance, low plug loss in the near-infrared band and excellent durability. This kind of material is prepared by forming a long rod or needle array of nano-metal particle structure in the glass, and the main preparation method is stretching-reduction method. The principle of polarization and performance testing of near-infrared polarized glass are introduced in detail. The current research status of main near-infrared polarized glass system and preparation technology of near-infrared polarized glass at home and abroad are reviewed. The development of near-infrared polarized glass is also prospected.
