A novel parallel optical delay detector for angle-of-arrival measurement is proposed and the measurement errors are experimentally studied and analyzed. Moreover, the measurement accuracy monitoring is investigated.
We investigate the dependence of nonlinear penalty on symbol-rate in polarisation-multiplexed coherent DQPSK WDM-transmission systems over an uncompensated SSMF link with a fixed spectral efficiency of 2 bit/s/Hz. The performance is found to be similar, irrespective of the symbol-rate.
We investigate the systematic influence of optical polarization effects and chromatic dispersion (CD) on digital timing phase estimation in receivers with coherent demodulation. It is shown by analysis and by simulation that half-Baud differential group delay (DGD) in combination with certain states of polarization (SOP) attenuates the clock tone such that the timing phase can not be estimated. Furthermore,...
We investigate the reduction in the duty-cycle for M-phase-shift-keyed transmission, demonstrating performance improvement in the range of 2-8 dB in nonlinear threshold (NLT) due to intrachannel-four wave mixing (IFWM) and nonlinear phase noise (NLPN).
In this paper, a sequential color light emitting diode (LED) backlight driving system for liquid crystal display (LCD) panels is proposed. Due to improvement on luminous efficacy, long life and wide color gamut, LED has gradually substituted for cold cathode fluorescent lamp as backlight The proposed driving system adopts sequential color scanning scheme to improve light utilization efficiency by...
