一种单纤双向光组件及滤波器的槽型限位结构
Abstract:
(EN)
A slot-type limit structure for a single-fiber bi-directional optical module and filter. The module comprises a silicon-based optical platform; along a laser transmission direction, a laser for emitting laser light, a lens, a filter and an optical fiber sequentially arranged on a laser transmission path, the filter being a filter which allows the emitted laser to go through and which reflects the laser light returned by means of the optical fiber; also a photodetector for receiving the laser light reflected by the filter, wherein the silicon-based optical platform is etched and formed with a limit structure for fixing the foregoing elements; further, a package structure for coordinating with the silicon-based optical platform, and for packaging the foregoing elements. In the above embodiment, by means of employing the silicon-based optical platform as a platform for supporting the elements, certain structures of the fixed elements are directly formed on the silicon-based optical platform. When compared with the single-fiber bi-directional optical modules in the prior art, the present invention does not require the use of an additional fixation structure, which simplifies the installation structure of the single-fiber bi-directional optical module, and facilitates the installation of the single-fiber bi-directional optical module.
(FR)
L'invention concerne une structure de limite de type fente destinée à un module optique bidirectionnel à fibre unique et un filtre. Le module comprend une plate-forme optique à base de silicium, le long d'une direction de transmission laser, un laser permettant d'émettre de la lumière laser, une lentille, un filtre et une fibre optique disposée séquentiellement sur une trajectoire de transmission laser, le filtre étant un filtre qui permet la traversée du laser émis et qui réfléchit la lumière laser renvoyée au moyen de la fibre optique; par ailleurs, un photodétecteur permettant de recevoir la lumière laser réfléchie par le filtre, la plate-forme optique à base de silicium étant gravée et formée au moyen d'une structure limite permettant de fixer les éléments précédents; en outre, une structure d'emballage destinée à la coordination avec la plate-forme optique à base de silicium, et à l'emballage des éléments précédents. Dans le mode de réalisation ci-dessus, en utilisant la plate-forme optique à base de silicium en tant que plate-forme de support des éléments, certaines structures des éléments fixes sont directement formées sur la plate-forme optique à base de silicium. Par rapport aux modules optiques bidirectionnels à fibre unique de l'art de la technique, la présente invention ne nécessite pas l'utilisation d'une structure de fixation supplémentaire, ce qui simplifie la structure d'installation du module optique bidirectionnel à fibre unique, et facilite l'installation du module optique bidirectionnel à fibre unique.
