We fabricated an eight-channel EADFB laser array sub-assembly using a flip-chip interconnection technique that provided a low crosstalk. We achieved clear eye openings for all eight lanes with 8 x 50-Gb/s simultaneous operation.
We have developed a highly compact monolithically integrated lightsource for 100GbE. Error-free transmission over 40-km on single-mode fiber under 100-Gbit/s operation is achieved, showing the usefulness of the device for future compact 100GbE transmitters.
We have developed 4 × 25-Gbit/s, 1.3-μm, monolithically integrated light source for 100-Gbit/s Ethernet (100GBASE-LR4) for the first time. Error-free transmission of 10-km on SMF under 100-Gbit/s (4 × 25-Gbit/s simultaneous) operation is demonstrated.
We developed a 4×25.8-Gbit/s EADFB laser array module for use as a 100-Gbit/s Ethernet transceiver. We demonstrated error-free transmission over a 10-km single-mode fiber at 100-Gbit/s with a modulation voltage of 1 V.
