Description
(1) 光導波路と該光導波路を伝搬する光波を変調するための変調電極とを有する変調基板と、該変調電極に印加される変調信号を生成するドライバ回路素子とを筐体内に収容した光変調器において、該ドライバ回路素子の上面側に変調信号を出力する出力端子を設け、該出力端子と該変調電極とを電気的に接続する配線を備えた配線基板が、該ドライバ回路素子と該変調基板との上側で両者に跨って配置されており、該配線基板は、該ドライバ回路素子から差動信号を受入れ、該変調電極には該差動信号の一方の信号のみを出力するよう構成されていることを特徴とする。
本発明は、図1乃至3又は図4乃至6に示すように、光導波路200と該光導波路を伝搬する光波を変調するための変調電極10とを有する変調基板1と、該変調電極に印加される変調信号を生成するドライバ回路素子2とを筐体(3)内に収容した光変調器において、該ドライバ回路素子の上面側に変調信号を出力する出力端子を設け、該出力端子と該変調電極とを電気的に接続する配線を備えた配線基板4が、該ドライバ回路素子と該変調基板との上側で両者に跨って配置されていることを特徴とする。
また、InPなどの半導体材料や有機材料など種々の材料を利用した基板も利用可能である。
図8の配線基板4の左側にはドライバ回路素子の出力信号が導入され、配線基板4上には、差動信号(S+,S-)と接地(G)に対応した配線40が設けられている。差動信号と接地の配置や配線の数は、ドライバ回路素子の出力端子に対応して設定される。また、図6の4つの差動信号を利用する場合のように、複数の変調信号を出力する場合には、配線基板4にも変調信号の数に対応して同様な配線パターンが並列に設けられる。なお、接地用の配線Gについては、隣接する配線間で共用する場合もある。
