Abstract
(EN)
The purpose of the present invention is to provide an optical module of a configuration in which a commercially available electronic component can be used, and the number of current generation circuits and electric wirings can be reduced. The optical module according to the present invention has an electronic component mounted on a separate board from a light wave circuit board provided with an optical component such as an optical switch, and is electrically connected by wire bonding with the separate board and the light wave circuit board. For this reason, the present optical module can use a commercially available electronic component. In addition, the present module has a configuration in which heaters of optical switches, which do not simultaneously flow currents, are grouped and a current from one current generation circuit is supplied to any one of the heaters in the group by means of one electric switch. For this reason, the present optical module does not have to be prepared with the same number of electrical switches and current generation circuits as the number of heaters.

Le but de la présente invention est de fournir un module optique d'une configuration dans laquelle un composant électronique disponible dans le commerce peut être utilisé et le nombre de circuits de génération de courant et de câblages électriques peut être réduit. Le module optique selon la présente invention comprend un composant électronique monté sur une carte séparée à partir d'une carte de circuit imprimé d'onde lumineuse pourvue d'un élément optique tel qu'un commutateur optique et est connecté électriquement par microcâblage filaire avec la carte séparée et la carte de circuit imprimé d'onde lumineuse. Pour cette raison, le présent module optique peut utiliser un composant électronique disponible dans le commerce. De plus, le présent module a une configuration dans laquelle des éléments chauffants de commutateurs optiques, qui ne font pas circuler de courants simultanément, sont groupés et un courant provenant d'un circuit de génération de courant est fourni à l'un des éléments chauffants du groupe au moyen d'un commutateur électrique. Pour cette raison, le présent module optique ne doit pas être préparé avec le même nombre de commutateurs électriques et de circuits de génération de courant que d'éléments chauffants.

市販の電子部品を使用でき、且つ電流発生回路と電気配線の数を削減できる構成の光モジュールを提供することを提供することを目的とする。 本発明に係る光モジュールは、光スイッチ等の光部品を備える光波回路基板とは別の基板に、電子部品を実装し、それぞれをワイヤボンディングで電気的に接続している。このため、本光モジュールは市販の電子部品を使用することができる。さらに、本モジュールは、同時に電流を流すことのない光スイッチのヒータをグループ化し、一つの電気スイッチで一つの電流発生回路からの電流をグループ内のヒータのいずれかに供給する構成である。このため、本光モジュールはヒータの数だけ電気スイッチと電流発生回路を用意する必要が無い。
