Abstract

We fabricated a 400-G flip-chip interconnection eight-channel EADFB laser array module. The flip-chip interconnection technique provides a higher modulation bandwidth and lower electrical crosstalk than the wire interconnection technique. The 3-dB bandwidth of the flip-chip interconnection subassembly was about 50 GHz. And the electrical crosstalk of the flip-chip interconnection module was suppressed to less than -20 dB below 35 GHz. We obtained clear eye openings for all eight lanes under eight-channel 50-Gb/s simultaneous operation after a 10-km SMF transmission.
