| Abstract(in English) | The rapid growth of data traffic requires high capacity optical transmission systems. To meet this demand, the baud rate, numbers of multi-level and wavelength multiplexing are increasing. The intensity modulation / direct detection (IMDD) method which can easily construct the system is used in the short reach applications. For 10 km reach system, 100 Gb/s is realized by 25 Gbaud ? NRZ ? 4-wavelength multiplexing and one of the most promising 400 Gb/s is realized by 56 Gbaud ? PAM4 ? 4-wavelength multiplexing. We developed the precise lens-assembly techniques based on the adhesive bonding and hammering. These techniques allow us to realize a compact TOSA which is suitable for the QSFP28 form factor. On the other hand, with the beyond 400 Gb/s scheme, the transmission distance which is applicable to the IMDD system is shortened due to the penalty increase, and the digital coherent system is used. The one of the issues when introducing the digital coherent system into a short range system is cost reduction. It is necessary to realize a high baud rate of 100 Gbaud, a narrow linewidth and high light output with low cost. In this presentation, we discuss the technologies that should be. |
