POLARIZATION GLASS, OPTICAL ISOLATOR AND METHOD FOR MANUFACTURING POLARIZATION GLASS

摘要

Provided is a polarization glass which contains shape-anisotropic metal particles orientationally dispersed in a glass base material. In the concentration distribution of the metal particles, in a traveling direction of polarizing light, the concentration is substantially zero at vicinities of surfaces on one side and the other side of the glass base material, gradually increases toward the other side of the glass base material from the one side, and the concentration is within a prescribed range in the glass base material, then, gradually reduces toward the other side.
