Description
以下、本実施形態1における撮像素子の構成の概略について説明する。
φ=(neff−n0)×2πh/λ (1)
で表わされる。この位相遅延量は光の波長λによって異なるため、同一の柱状構造体121に入射した光に対して波長域(色成分)に応じて異なる位相遅延量を与えることができる。また、柱状構造体121の底面および上面が正方形であるため、偏光方向を変化させた場合においても、位相遅延効果を含む光学特性に変化はない。さらに、neffは構造寸法の関数であることが知られており、n0<neff<n1の値をとる。したがって、図4(a)、(b)に示す例では、柱状構造体121の幅wを変化させることで、任意の位相遅延量を設定することが可能である。
次に、本発明の実施形態2に係る撮像素子について説明する。
