Abstract
【解決手段】分離可能な変調器アーキテクチャが開示される。この変調器はキャビティ上で可撓性の層から吊り下げられたミラーを有する。可撓性の層はまた、支柱と支持体をミラーのために形成する。別の分離可能な変調器アーキテクチャは、キャビティ上に吊り下げられたミラーを有する。この変調器は、支柱と支持体によって支持される。支柱は支柱プラグ上に可撓性の層を含む。バス構成が支柱上に配置された可撓性の層の上に形成されてもよい。
Description
本発明の一実施形態は、分離可能な変調器構成である。前記変調器は、キャビティの上の可撓性の層から吊り下げられたミラーを有する。前記可撓性の層はまた、前記ミラーのための支持体と支柱とを形成し得る。
図1は、干渉応用変調器の側面図を示す。変調器2は、透明な基板10の上に配置されるが、これは通常ガラスである。1次(primary)ミラー12は、干渉応用変調器のアレイの個々の要素のアドレス指定を可能とする電極の表面に配置される。キャビティ14の上には、2次(secondary)ミラー16が吊り下げられるが、これは膜15の上に載っているか、膜15の一部である。13のような支持アームは、膜15と同じ層の一部であっても、ミラー16を支持しても、それを支柱18に取り付けてもよい。支持アームと膜15は可撓性を有する。これは、2次ミラー16がキャビティ14内に移動されることを可能にし、2次ミラーを1次ミラーに近づけ、それによってキャビティの干渉特性に影響を及ぼす。
