statistical theory of Polarization Dispersion in single mode fibers
Journal of Lightwave Technology, 1991Co-Authors: G J Foschini, C. D. PooleAbstract:An analytical characterization of Polarization Dispersion measurements is presented. The authors report the solution of Poole's stochastic dynamical equation for the evolution of the Polarization Dispersion vector with fiber length. The authors extend this to a more complete description by considering small, second-order Dispersion effects through the frequency derivative of the Dispersion vector. The complete analytical solution is seen to accord with what were originally empirically derived features of the joint probability distribution of the Polarization Dispersion vector and its frequency derivatives. Among the analytically determined properties are the Gaussian probability densities of the three components of the Dispersion vector, and the hyperbolic secant (soliton shaped) probability densities of the components of the derivative of the Dispersion vector. >

dynamical equation for Polarization Dispersion
Optics Letters, 1991Co-Authors: C. D. Poole, J H Winters, J A NagelAbstract:Polarization Dispersion in single-mode fiber that contains arbitrary birefringence is described through a vector differential equation. Monte-Carlo simulations using this equation show good agreement with experimental measurements in a randomly birefringent fiber and with a previously reported analytic expression for the length dependence of the Dispersion. We also correct an error made in earlier research and show that the probability density function for the magnitude of the Dispersion at long lengths is Maxwellian rather than Gaussian as previously reported.

Polarization Dispersion compensated AWG with angled star couplers based on silica-on-silicon
Asia Communications and Photonics Conference, 2012Co-Authors: Tingting Lang, Jian-jun HeAbstract:A Polarization compensated AWG with angled star couplers based on silica-on-silicon is demonstrated. Five AWGs with different Polarization compensator parameter γ corresponding to different incident/diffraction angles are fabricated. The PDλ of the central channels is less than 0.02nm.

Polarization Dispersion compensated arrayed waveguide gratings design based on silicon nanowires
2011Co-Authors: Tingting Lang, Jian-jun HeAbstract:A simple method to design Polarization Dispersion compensated arrayed waveguide gratings based on silicon nanowires is proposed using angled star couplers with different diffraction orders for TE and TM Polarizations. Polarization Dispersion compensation for all channels is achieved by using a 380nm×220nm silicon waveguide with an upper-cladding of SU-8. The simulation results demonstrate the validity of the design.

Uniform Polarization-Dispersion Compensation of All Channels in Highly Birefringent Silicon Nanowire-Based Arrayed Waveguide Grating
IEEE Photonics Technology Letters, 2011Co-Authors: Tingting Lang, Lei Wang, Jian-jun HeAbstract:A design method for compensating Polarization Dispersion in arrayed waveguide gratings (AWGs) based on highly birefringent silicon nanowire waveguides is proposed by using angled star couplers in combination with different diffraction orders for TE and TM Polarizations. Polarization-Dispersion compensation for all output channels is achieved with the maximal Polarization-dependent wavelength shift of 0.025 nm in an eight-channel AWG with 200-GHz spacing using 380 nm × 220 nm silicon waveguide with SU-8 upper-cladding.

Effects of random Polarization Dispersion on soliton propagation in optical fibers
Proceedings of TENCON '93. IEEE Region 10 International Conference on Computers Communications and Automation, 1993Co-Authors: Xiongyan Tang, Peida YeAbstract:The effects of random Polarization Dispersion on soliton propagation in optical fibers are investigated numerically by considering the random rotation of the birefringence axes and the random fluctuation of the magnitude of the Polarization Dispersion. It is shown that with the correlation length of the random Polarization Dispersion increases, the effects on soliton propagation become more serious. >

Evaluation of Dispersions penalty in an optical coherent PSK transmission system
Microwave and Optical Technology Letters, 1991Co-Authors: Xiongyan Tang, Peida YeAbstract:A transmission system model suitable for analyzing both chromatic Dispersion and Polarization Dispersion effects on any coherent optical transmission systems is proposed. Applying this model, the waveform distortion due to both Dispersions is calculated for a coherent PSK signal. The Dispersions penalty in a coherent PSK system and in a coherent CPFSK system is compared.
