Abstract (in Japanese) (See Japanese page) 
(in English) High-order multi-level modulation formats, such as 16-QAM and 64-QAM, are promising techniques for constructing beyond-100-Gb/s/ch optical transmission systems. We have developed an ultrahigh-speed DAC with InP HBT technology for such systems. The fabricated DAC can operate at a sampling rate of up to 28 GS/s with a low power consumption of 0.95 W, which is lower than any other previously reported DACs with a sampling rate above 20 GS/s. The DAC was assembled into a metal package for use in an optical transmission experiment, where it provides a clear multi-level signal. The DAC module can be applied to beyond-100-Gb/s/ch multi-level optical transmission systems.
