We transmit coded modulation PDM-QPSK over 6,370 km of dispersion managed NZDSF spans. Coded modulation enables absolute phase detection without pilot symbols and provides 1.5 to 4 dB Q-factor margin.
We experimentally investigate the scaling of nonlinear impairments with distance and spectral efficiency in 40G and 100G dispersion-uncompensated long-haul transmission.
We demonstrate a pilot-symbol assisted joint polarization carrier phase estimation technique that detects cycle slip and avoid error propagation. Coherent detection without differential coding is feasible when the cycle slip probability is less than 10-3.
We experimentally investigate the effect of residual disorder on the dispersion curve of light near a band edge. A Fourier space imaging technique accurately distinguishes the propagating regime from diffusive transport and evanescent regime in planar photonic crystal. We highlight and quantify the impact of the disorder on the group velocity near a band edge. We stress that the achievement and determination...
In this paper, we will focus on CCW waveguides, which building block consists of a photonic crystal cavity of a moderate Q-factor, i.e., Q~103. We will show that despite increased radiation loss that cannot be avoided in the present design, a chain of more than 50 cavities can be coupled, as confirmed by both transmission experiment and near-field imaging. Moreover, formation of a smooth and continuous...
Remarkable differences in action potential properties between the Purkinje fibre and ventricular cells may lead to abnormalities in excitation conduction through the Purkinje-ventricular junction (PVJ) and arrhythmogenic behaviour. We develop a family of electrophysiologically detailed computer models for rabbit epicardial, midmyocardial and endocardial ventricular myocytes, as well as the rabbit...
We have developed a three-dimensional computational wedge model of canine cardiac ventricular wall electro-physiology that incorporates biophysically detailed, spatially heterogeneous excitation, and high-resolution geometry and fibre orientation. Isolated cell model electrophysiological characteristics reproduce the experimentally observed characteristics under control conditions, and under conditions...
