hollow core conjoined tube fiber for penalty free Data Transmission under offset launch conditions
Optics Letters, 2019Co-Authors: Xiaocong Wang, Wei Ding, Yingying Wang, Shoufei Gao, Xin Zhang, Yizhi Sun, Zhangyuan Chen, Pu WangAbstract:Three types of hollow-core fibers, i.e., photonic-bandgap fiber, negative-curvature fiber, and conjoined-tube fiber, are compared in terms of Data Transmission performance. Their group velocity dispersions and group indices are measured in detail by using low-coherence interferometry. Whilst all three fibers show good performance with an optimized central launch, they behave differently under offset launch for 10 Gbit/s on–off keying Transmission. We use a Q2-factor analysis method to gain insight into the Data Transmission over a hollow-core fiber. The low-loss, low-intermodal crosstalk conjoined-tube fiber shows great resilience to bending and offset launch compared to the other two hollow-core fibers, enabling genuine penalty-free Data Transmission in realistic environments.

ultralow loss hollow core conjoined tube negative curvature fiber for Data Transmission
Optical Fiber Communication Conference, 2019Co-Authors: Xiaocong Wang, Wei Ding, Yingying Wang, Shoufei Gao, Xin Zhang, Yizhi Sun, Zhangyuan Chen, Yingchao Xin, Pu WangAbstract:We present a hollow-core conjoined-tube negative-curvature fiber with unique merits of ultralow loss of 2 dB/km at telecom band and launch-insensitive response to the Data Transmission in 10-Gb/s OOK test.

multi rate sequential Data Transmission
International Symposium on Information Theory, 2013Co-Authors: Cheuk Ting Li, Shenghao Yang, Raymond W YeungAbstract:We investigate the Data Transmission problem in which a sequence of Data is broadcast to a number of receivers via erasure channels with different erasure probabilities. Accordingly, the receivers wish to decode the Data sequentially at different rates. We present a formulation of the problem and propose an optimal coding scheme. Our results can be employed in the streaming of a video clip by broadcasting, so that receivers with different bandwidths can play the video at different speeds. Specifically, receivers with sufficiently large bandwidth can play the video at normal speed, while others can play the video with pauses, or at a slower speed using time-scale modification. Our results completely characterize the fundamental tradeoff between the available bandwidth and the playback speed of the video.

self powered system with wireless Data Transmission
Nano Letters, 2011Co-Authors: Yan Zhang, Long Lin, Robert L Snyder, Zhong Lin WangAbstract:We demonstrate the first self-powered system driven by a nanogenerator (NG) that works wirelessly and independently for long-distance Data Transmission. The NG was made of a free cantilever beam that consisted of a five-layer structure: a flexible polymer substrate, ZnO nanowire textured films on its top and bottom surfaces, and electrodes on the surfaces. When it was strained to 0.12% at a strain rate of 3.56% S–1, the measured output voltage reached 10 V, and the output current exceeded 0.6 μA (corresponding power density 10 mW/cm3). A system was built up by integrating a NG, rectification circuit, capacitor for energy storage, sensor, and RF Data transmitter. Wireless signals sent out by the system were detected by a commercial radio at a distance of 5–10 m. This study proves the feasibility of using ZnO nanowire NGs for building self-powered systems, and its potential application in wireless biosensing, environmental/infrastructure monitoring, sensor networks, personal electronics, and even national s...
