3Dプリンタを用いた円二色性フィルタの製作

抄録

In this paper, we report fabrication of a circular dichroic filter with a 3D printer. Microscale chiral structures exhibit strong circular dichroism in the infrared region, and are promising for optical filter applications. The optical properties of microscale chiral structures that absorb one side of circularly polarized light and transmit the other were evaluated by simulation. Prototype chiral structures were fabricated with a 3D printer and we confirmed that microscale chiral structures can be fabricated with a 3D printer. This leads to realizing fabrication of single layered thin optical filter that absorb one side of circularly polarized light with a 3D printer.
