Encapsulated light source with coupled fiberguide

摘要

A laser is coupled to an optical fiber in an hermetic encapsulation by locking a portion of the fiber near the laser in a body of solder. With the laser energized, the position of the optical fiber is adjusted within an aperture through the solder body to optimize the light output at the end of the fiber. The solder body then is heated to cause flow around the fiber and cooled to lock the fiber in position.
