Description
IR=10×n×log(F/B)
図3のような形態の素子を製作し、その性能をテストした。この過程で反射型偏光器100としては、金属ワイヤーグリッド偏光子(Wire Grid Polarizer)を使ったのであり、再帰反射器200としては反射型傾斜ルーバーフィルムを適用したのであり、リターダー300としては、Thorlabs社の製品(WPQ05M−532)を使った。前記のような素子に対してCoherent社のGenesis MX SLMレーザーを入射(10mW出力)させて素子をテストした。このような方式で得られた正方向透過率は約76%程度であり、逆方向透過率は約36%程度であり、孤立度(IR)は約3.2dB程度であった。
