Submount and connector assembly for active fiber needle

摘要

A connector assembly includes an active fiber needle 1 having a passive or active optical device 6 connected to an end face 7 of a thick metallized coating 4 and a cup-shaped mount 10 for hermetically enclosing the optical device. The mount 10 hermetically encloses the optical device 6 and provides heat dissipation and electrical connections for optical device 6. The cup-shaped mount may include a ceramic tubular sleeve hermetically sealed to the metal coating 4 on the fiber needle 1 about a central bore 12A thereof. Electrical connections between the optical device 6 and devices external to the mount may preferably be provided through a spring contact 18 which is soldered to terminals on device 6 and has at least one leg 18A, 18B extending through the hermetically sealed cup-shaped housing 10. Other embodiments of electrical lead connections may be provided by wire bonds 24 between device 6 and external metallization surfaces 26A.
