Language：English Publisher：The Institute of Electronics, Information and Communication Engineers
This work proposes a method for the alignment of the signal and pilot tone paths in self-homodyne coherent-detection systems to achieve phase noise cancelation without the need for traffic interruption. The method is demonstrated on a spatial division multiplexing transmission system using a 10.1 km 19-core multi-core fiber. It is shown that sub-centimeter resolution is achievable with penalties under 0.5 dB.

Precise chirp parameter measurement of asymmetric Mach-Zehnder modulators with active Y-branch
Yuya Yamaguchi, Yuki Yamada, Atsushi Kanno, Tetsuya Kawanishi, Masayuki Izutsu, Hirochika Nakajima
IEICE Electronics Express 10 ( 12 ) 2013
Language：English Publishing type：Rapid communication, short report, research note, etc. (scientific journal)
For precise chirp parameter control, we investigated xcut LiNbO3 single-drive asymmetric Mach-Zehnder modulators with extinction-ratio adjustable active Y-branch structures, which can enhance on-off extinction ratio. The chirp parameter of the modulated output was precisely measured by using high extinction ratio operation. Experimental results show that it is possible to fabricate modulators with desired chirp parameters. © IEICE 2013.

We demonstrate a significant reduction of the required carrier-phase estimation rate for self-homodyne multi-core fiber systems by analyzing experimental data with implementation-constrained digital signal processing, which could enable an improvement on receiver energy consumption.

A Chirp Measurement Method for Integrated Parallel Mach-Zehnder-Modulators

112 ( 280 ) 17 - 21 2012.11
Language：English Publisher：The Institute of Electronics, Information and Communication Engineers
In this paper, we propose a method to measure total chirp of integrated parallel Mach-Zehnder-type modulators by analyzing optical spectrum components. The method can be applied to characterize the modulators without any restriction on extinction ratio and permit to evaluate the chirp parameter at a specific frequency. An experiment measurement is also conducted to demonstrate the proposed method for an optical FSK modulator. The obtained result reveals the effectiveness of this chirp measurement method.

電子情報通信学会技術研究報告 112 ( 280(MWP2012 46-51) ) 23-26 - 26 2012.11
Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers
Dual-polarization Quadruture Phase-Shift Keying (DP-QPSK) modulator can simply generate Radio-over-Fiber (RoF) signal. DP-QPSK modulator was developed for 100 Gigabit Ethernet (GbE) and consists two IQ modulator. It is utilized for generation two QPSK signal for each polarization. In this study, we propose that one polarization is worked as RoF-LO signal using single sideband suppressed carrier modulation, and other polarization for QPSK modulation. This technique can generate 25GHz 5Gbps QPSK RoF signal.
