Polarizing device, and method for manufacturing the same |
摘要 |
A polarizing element 20 has a first undulating structure in which a plurality of linear first recesses 22 are formed parallel to one another in one surface of a transparent substrate 21, and a dielectric layer 30 made from silicon dioxide is formed on the surface of the first undulating structure to produce a second undulating structure. The second undulating structure has formed therein second recesses 32 having a width W and a depth H, with second projections 33 having a width d intervening between adjacent second recesses 32. A thin-film-shaped conductive body 13 of width W and depth H is embedded in each of the second recesses 32.
