ここで、σ0は、例えば基準温度での残留応力であり、kは定数である。一般的な基準温度は、約摂氏25度の室温である。一実施形態におけるこれらのパラメータ間の関係の例として、温度が摂氏1度上昇するごとに、可動反射層中の応力が2MPa変化し、動作電圧が〜11mVシフトすることになる。一般的な実施形態では、干渉変調器60の層14内の応力(σ)は、引っ張り応力であり、このことは、σがゼロ以上であることを意味する。
ΔCTE=α1-α2 式4
ここで、α1=13.0×10-6/℃(ニッケルのCTE)、α2=3.76×10-6/℃(Corning Glass No.1737のCTE)である。次に、熱歪みεTは、次式で表されることがある。
εT=(ΔCTE)(ΔT) 式5
ここで、ΔTは、基準温度に対する温度変化である。次に、結果として生じる熱応力は、次式で表されることがある。
σT(T)=ElεT=El(ΔCTE)(ΔT) 式6
ここでElはニッケルの弾性率であり、ΔTは基準温度に対する温度変化である。次に、作動電圧は、以下の式のどれかで示されるように温度の関数として表されることがある。
