An improved monitoring and control system for a laser (3034) in a header assembly (3020) of a transmitter optical subassembly (TOSA 3000). The system including one or more monitor photodiodes (MPD 4000) is positioned together with the laser on a component submount (3033). The submount in turn is mated with a multi-layer platfom (MLP 3030) that forms part of the header assembly. The MLP hermetically extends through the header assembly to provide a plurality of electrical interconnects for the laser, MPD(s), and other submount components.

Cette invention se rapporte à un système de contrôle et de commande amélioré pour un laser (3034) dans un ensemble collecteur (3020) d'un sous-ensemble optique d'émetteur (TOSA 3000). Ce système comprend une ou plusieurs photodiodes de contrôle (MPD 4000) et il est placé avec le laser sur un sous-support de composants (3033). Ce sous-support est à son tour accouplé à une plate-forme multicouche (MLP 3030) qui fait partie de l'ensemble collecteur. La plate-forme MLP s'étend hermétiquement à travers l'ensemble collecteur pour former plusieurs interconnexions électriques pour les photodiodes MPD du laser ou pour d'autre composants du sous-support.
