Inter­chan­nel Non­lin­ear­i­ties in Polar­iza­tion-Mul­ti­plexed Trans­mis­sion

35th Euro­pean Con­fer­ence on Opti­cal Com­mu­ni­ca­tion 2009

Abstract: We exam­ine the impact of cross-polar­iza­tion mod­u­la­tion and cross-phase mod­u­la­tion in polar­iza­tion-mul­ti­plexed sys­tems by means of com­put­er sim­u­la­tions and show how sym­bol-inter­leav­ing reduces the XPolM-relat­ed penal­ty.

Down­load the con­fer­ence paper.

Down­load the pre­sen­ta­tion slides.

Notes: The fig­ures in the pre­sen­ta­tion slides dif­fer slight­ly from those in the paper, because in the paper we per­formed the sim­u­la­tions with a CW (PolDM) sub­chan­nel as probe while for the pre­sen­ta­tion we repeat­ed the sim­u­la­tions with two QPSK-mod­u­lat­ed sub­chan­nels. The non­lin­ear thresh­olds may seem quite high for NRZ DWDM inter­fer­ers, com­pared to oth­er pub­li­ca­tions, but we used a com­par­a­tive­ly large val­ue of resid­ual dis­per­sion per span (256 ps/nm/km, cor­re­spond­ing to 16 km uncom­pen­sat­ed SSMF) which effec­tive­ly sup­press­es inter­chan­nel dis­tor­tions from NRZ neigh­bors.
