Abstract

As applications of fiber optic communications have spread from the trunk lines to the subscriber loops and LANs, requirement for low cost and small size has become severe on the key components, especially on the laser diode modules. Conventionally, totally automated active alignment, optimizing the optical axis emitting the LD , has made the LD module cost lower and lower.[1] Recently, passive alignment approaches have been challenged, to realize much lower cost, smaller size and higher density mount.
