Abstract :
The first compact electroabsorption modulators integrated with distributed-feedback (EADFB) laser array module using flip-chip interconnects have been fabricated for a 400 Gbit/s transceiver. Eight 50 Gbit/s EADFB lasers and an optical multiplexer were monolithically integrated on one chip in an area of only 3.2 × 4.8 mm. The flip-chip interconnects provide a higher modulation bandwidth. Clear eye opening was achieved for all eight lanes under 50 Gbit/s operation.
