Abstract
【解決手段】 受動的に温度補償される光グレーティング(回折格子)の装置は、第1の固定側壁と、CTEが小さい材料からなるレバー・アームの間の筐体を横切って引伸ばされている光グレーティングを具備したCTEが小さい材料の筐体を含む。CTEが大きい材料からなる伸張要素は筐体に取り付けられ、かつレバー・アームと接触するように配置されて、温度変化によって伸張要素の寸法が変化するとレバー・アームを回転させる。レバー・アームと伸張要素の寸法を適切に定めて、レバー・アームの動きにつれて引っ張り、あるいは圧縮されてグレーティングに加えられる歪を調節することにより、温度の関数であるグレーティング波長の変化の補正が可能となる。
