Influence of channel misalignment of time-interleaved DAC on sensitivity degradation in coherent optical receivers

Abstract (in Japanese) (See Japanese page) 
(in English) The demand for higher-speed digital-to-analog converters (DACs) in the optical transmitter is increasing as the data rate increases. The time-interleaved architecture in DACs is one of the ways which realize high sampling speeds without relying on high clock rates. In this paper, we evaluate the sensitivity degradation in coherent optical receivers caused by channel misalignment of such time-interleaved DACs in the transmitter, focusing on QPSK and 16-QAM signals.
