Description
C.Marxerほか、「Micro-Opto-Mechanical 2x2 Switch for Single Mode Fibers based on Plasma-Etched Silicon Mirror and Electrostatic Actuation」(preceding 11th IEEE Workshop on Micro-Electro-Mechanical System、1998年、233〜237頁)
Rav(X)=∫R(X,Y)・Φ(Y)dY / ∫Φ(Y)dY
(ここで、Xは第1および第2の光軸を含む平面と反射部との交線に沿って延びるX軸方向の座標、Yは反射部上でX軸と垂直に延びるY軸方向の座標、R(X,Y)はXY平面上における反射率分布、Φ(Y)は第1の光路から反射部に入射する光のY方向強度分布)で定義される関数Rav(X)が異なる二つのX座標間で少なくとも10%から90%まで変化するような分布を有していてもよい。
Rav(X)=∫R(X,Y)・Φ(Y)dY / ∫Φ(Y)dY (1)
で定義される関数Rav(X)を用いる。図2に示されるように、Xは基準平面14とミラーの反射面との交線に沿って延びるX軸方向の座標であり、Yはミラーの反射面と平行な平面においてX軸に垂直な方向の座標である。R(X,Y)は、XY平面内における反射率分布である。ここでは、反射面23aの存在するXY座標での反射率を100%とし、反射面23aの存在しないXY座標での反射率を0%とする。Φ(Y)は、光導波路11から反射面23に入射する光のY方向強度分布である。
