摘要： A method for bonding flat glasses that adjusts proper conditions of bonding surfaces of the flat glasses and then compresses the flat glasses until two flat glasses bind by Ven Der Wall's interaction, an inherent interaction between molecules, to achieve a combined lens assembly. Moreover, heating may be used in the bonding method to decrease time for bonding the flat glasses and to enhance bonding strength. The combined lens assembly is simply bonded by molecular interaction without any adhesive or cohesive solution used in conventional bonding techniques.

摘要： A method of fabricating a WDM unit consists of attaching a first and a second GRIN lenses to opposite faces of a WDM filter. A dual fiber pigtail and a single fiber pigtail are mounted in corresponding glass tubes. The glass tube with the dual fiber pigtail and the glass tube with the single fiber pigtail are mounted on the second GRIN lens and the first GRIN lens respectively. The position of the dual fiber pigtail and the single fiber pigtail are adjusted with respect to the second GRIN lens and the first GRIN lens respectively to obtain the best optical property. The invention prevents the WDM filter from tilting during temperature variation by sandwiching the WDM filter in between the two GRIN lenses, and further prevents the WDM unit from increasing the reflection loss and insertion loss.
