| Abstract(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 at the transmitter, focusing on QPSK and 16-QAM signals. |
