• Article: Direct Measurement of Vector Polarization-Mode Dispersion From Repeated Random Data by Use of Linear Optical Sampling

  [show abstract] [hide abstract]
  ABSTRACT: Polarization-dependent optical sampling techniques measure the complex electric field, allowing one to monitor the degrading effects of a communication channel. Here we show the ability to extract the polarization-mode dispersion of the transmission channel from a remote measurement of transmitted repeated 10-Gb/s differential phase-shift keying modulated data. This approach is independent of modulation format and data rate. We demonstrate results both with and without referencing to the laser phase. We achieve a differential group delay resolution of 0.2 ps for an unreferenced measurement.

  Conference Proceeding: Chromatic dispersion measurement error caused by source amplified spontaneous emission

  [show abstract] [hide abstract]
  ABSTRACT: We demonstrate the degrading effect of noise from amplified spontaneous emission on measurements of chromatic dispersion using the modulation phase-shift method. Dramatic performance improvement is achieved with a narrow-band tracking filter.
