Multichip optical transmitter module for chip-to-chip interconnection on optical PCBs

摘要

A multichip module of an optical transmitter, which consists of flip-chip bonded 1/spl times/4 VCSELs on a CMOS driver array IC, is fabricated and demonstrated. The -3 dB bandwidth and adjacent crosstalk of the hybrid integration multichip module are about 4.5 GHz and less than -30 dB, respectively. The whole integrated multichip volume is 1.1/spl times/1.2/spl times/0.52 mm/sup 3/ for four channels.
