Technical report of IEICE. OFT 111 ( 381 ) 33 - 36 2012.01
Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers
The ever-increasing demand for high data transmission capacities has necessitated the use of alternative wavebands and the development of methods for enhancing the transmission capacities of existing photonic networks. Polarization-division-multiplexing (PDM) and wavelength-division-multiplexing (WDM) are essential techniques for enhancing the capacity of photonic networks and facilitating the efficient use of optical frequency resources. We constructed the ultra-broadband PDM and WDM photonic transport system in the T-band (Thousand-band, 1000〜1260-nm) and C-bands (Conventional-band, 1530〜...

We discuss a concept of a coherent optical/wireless seamless network and W-band high-speed wireless transmission technique using RoF technology and optical digital coherent detection technique. Multi-level modulation/demodulation and photonic direct up-conversion technique can provide high-speed and low delay transmission of optical and wireless shared signals.

IEICE technical report 111 ( 150 ) 163 - 166 2011.07
Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers
Purpose of this experiment is generating picosecond pulse in the 1 μm region where expected as a new wave length range. Our pulse generation system uses MaclrZehnder-modulation-based flat comb (MZ-FCG). Because MZ-FCG has simple configuration and high controllability. Continuous wave (CW) light led to the MZ-FCG driven by two radio frequency sinusoidal signal. And MZ-FCG modulated CW light to the ultra flat comb signal. In time domain we can observe the ultra flat comb as picosecond pulse. By this system we succeed to generate lO.lps-width and repetition rate of 12.5GHz at 1060nm wave-length .

We demonstrate 20 Gb/s W-band QPSK transmission over the air. Optically synthesized 20 Gb/s QPSK signal with RoF technique is converted to the radio signal using direct optical upconversion technique with a high-speed photodetector. Transmitted W-band radio signal was detected and demodulated with a W-band digital receiver. The observed bit error rates was achieved 10〜6 with a distance of 30 mm.

Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers
The ever-growing demand for high data transmission capacities has created a need for the use of alternative wavebands and the development of methods for enhancing the transmission capacities of photonic networks. We recently focused on a use of a 1.0-μm waveband as namely a T-band (Thousand-band) to pioneer ultra-broad optical frequency resources for the optical communications. In this paper, error-free polarization division multiplexed (PDM) 10-Gbps × 2-PDM transmissions over a 3.7-km holey fiber in the T-band is successfully demonstrated for the first time.

Technical report of IEICE. OCS 111 ( 122 ) 63 - 66 2011.07
Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers
We propose a polarization-multiplexing QPSK modulator for synthesis of a 16QAM signal. The generation mechanism of 16QAM is based on an electro-optic vector digital-to-analog converter, which can generate optical multilevel signals from binary electric data sequences. This modulator is utilized a dual-polarization MZM, outputting two QPSK signals with orthogonal polarization. The QPSK signals are superposed by a polarizer, in which the amplitude ratio between them is precisely controlled by rotating the polarizer to arrange the 16 symbols equally. Generation of 40 Gb/s 16QAM with a bit erro...

Future large-scale data transmission requires new technologies to overcome the capacity limit of conventional optical fibers. Spatial division multiplexing using multi-core fibers is a strong candidate for such technology. In this paper, we present details of our multi-core fiber and spatial division multiplexer/demultiplexer, which is also a key device for multi-core fiber data transmission.
