Abstract
High-frequency lasers have been flip-chip mounted on silicon motherboa rds. Small-signal modulation bandwidths around 24 GHz were obtained. I t was shown that the bandwidth was not limited by extrinsic parasitics associated with the mounting scheme. Lasers were passively aligned to single mode fibers in V-grooves with the self-aligning solder bump te chnique. By passive alignment 50% of maximum coupling efficiency obtai ned by active alignment was achieved.
