Structured polarizer and method for manufacturing the same

摘要

A structured polarizer includes a substrate including a dielectric material including elongated metal particles embedded to form a polarizing layer including a plurality of first polarizing regions having first elongated metal particles collectively aligned along a first direction and a plurality of second regions having second metal particles, the first polarizing regions and the second regions adjoining each other, the first metal particles being in the same plane as the second metal particles, a degree of polarization with respect to the first direction in the first polarizing regions at between 0.5 μm and 1 μm from a boundary between the first polarizing regions and the second regions being more than 90%, and a degree of polarization with respect to the first direction in the second regions at between 0.5 μm and 1 μm from the boundary between the first polarizing regions and the second regions being less than 10%.

1. A structured polarizer, comprising:
a substrate being formed of a dielectric material in which elongated metal particles are embedded such to form a polarizing layer, the polarizing layer comprising a plurality of first polarizing regions having first elongated metal particles being collectively aligned along a first direction and a plurality of second regions having second metal particles, wherein the first polarizing regions and the second regions are arranged side by side such to adjoin each other,wherein the first metal particles of the first polarizing regions are arranged in a common plane of the polarizing layer as the second metal particles of the second regions,
wherein a degree of polarization with respect to the first direction in the first polarizing regions at a distance between 0.5 μm and 1 μm from a boundary between the first polarizing regions and the second regions is more than 90%, andwherein a degree of polarization with respect to the first direction in the second regions at a distance between 0.5 μm and 1 μm from the boundary between the first polarizing regions and the second regions is less than 10%.
