dispersive effects monitoring for rz data by adding a frequency shifted carrier along the Orthogonal Polarization State
Journal of Lightwave Technology, 2005Co-Authors: T Luo, Zhongqi Pan, Y Wang, Yoel Arieli, Alan E WillnerAbstract:As optical systems approach high speed and long distances, dispersive effects [chromatic dispersion (CD) and Polarization-mode dispersion (PMD)] can severely distort optical signals in the transmission link. It is important to dynamically monitor the dispersive effects in order to achieve high performance. We propose a method for dispersive effects monitoring by adding a frequency-shifted carrier along the Orthogonal Polarization and measuring the generated radio frequency (RF) clock power. Using this technique, PMD monitoring is isolated from CD effect and the CD information can be simultaneously obtained. We experimentally demonstrate this technique in a 10 Gb/s return-to-zero (RZ) system by adding an Orthogonal frequency-shifted carrier using an acoustooptic (AO) shifter.

chromatic dispersion insensitive dgd monitoring by adding a frequency shifted carrier along the Orthogonal Polarization State
Lasers and Electro-Optics Society Meeting, 2003Co-Authors: T Luo, Zhongqi Pan, Y Wang, A Yoel, Alan E WillnerAbstract:We demonstrate accurate DGD monitoring by adding a frequency-shifted carrier along the Orthogonal Polarization State and extracting the regenerated RF power near the bit-rate frequency. This monitoring signal is insensitive to chromatic dispersion.

microwave vector signal transmission over an optical fiber based on iq modulation and coherent detection
Optics Letters, 2014Co-Authors: Yang Chen, Tong Shao, Aijun Wen, Jianping YaoAbstract:A novel approach to transmitting two vector signals using a single optical carrier based on IQ modulation and coherent detection is proposed and demonstrated. In the proposed system, two quadrature phase-shift keying (QPSK) signals are IQ modulated on an optical carrier with one Polarization State using a dual-parallel Mach-Zehnder modulator (DP-MZM). The optical carrier with an Orthogonal Polarization State is not modulated but transmitted with the modulated optical wave. At the receiver, the two Orthogonally polarized light waves are separated and sent to a coherent detector, where the two QPSK signals are separated and demodulated. An experiment is performed. The transmission of two QPSK signals at 2 GHz with a data rate of 1 Gbps is implemented over a 25 km single-mode fiber. The performance of the transmission in terms of error vector magnitude is evaluated.
