| Abstract(in English) | In 100GbE, a multi-lane LAN-WDM system, in which four 25-Gbit/s light sources with different waveglengths are used for the transmitter, was employed. For beyond 100G LAN applications, it is almost unavoidable to use multi-lane system. At the same time, increasing the data rate of serial lanes is also a very important for reducing the number of lanes and the whole size of the transmitter. Here, we developed 1.3-um EADFB lasers with the modulation speed of over 25-Gbit/s for beyond 100G parallel LAN applications. The EADFB lasers developed here can be operated at the modulation speed of 50-Gibt/s and we obtained very clear eye openings up to 40-km transmission with semi-cooled operation (45 degree Celcius). Furthermore, we fabricated a monolithically integrated light source by integrating four these EADFB lasers and developed an ultracompact TOSA. By using the TOSA, 40-Gbit/s operation per channel was confirmed. |
