摘要

The introduction of customer access services require low cost laser modules capable for operation in a wide temperature range. We report on optimization of laser structures for wide temperature characteristics of 1.55 /spl mu/m DFB lasers. Single lasers conventionally mounted and laser arrays flip-chip mounted on silicon-motherboards by Au/Au thermo compression bonding show excellent reliability. Stability of the laser-fibre coupling was high in temperature cycling and burn-in.
