Abstract
This study analyzes the bit-error-rate characteristics of Stokes-vector modulation-demodulation systems employing optically preamplified receivers. We derive unified analytical formulae for the bit-error rate of binary, quad, and octal modulation formats, in which Stokes vectors are modulated in a binary manner per dimension. The receiver sensitivities estimated from the derived bit-error-rate formulae are examined by analyzing the probability-density function of noise in the Stokes-vector direct-detection receiver. In addition, the bit-error-rate formulae enable a comprehensive comparison of the sensitivity among various optical receivers, such as coherent, direct-detection, optically differential direct-detection, and Stokes-vector direct-detection receivers.
