Abstract

Novel self‐organized nanograting structures with periodically assembled crystalline and amorphous phases are created in La₂O₃–Ta₂O–Nb₂O₅ glass by an ultrafast laser. Heat accumulation and the Ta₂O₅ content strongly contribute to the nanograting formation. The fabricated nanograting arrays exhibit a broadband polarization‐dependent attenuation effect in the near‐infrared region, which indicates the potential uses in the optical information processing at communication wavelengths.
