Abstract(in English) | Demodulation of multi-level polarization-modulation optical signals can be done via Stokes-vector direct detection followed by digital signal processing. In this paper, we first describe the principle of operation of direct-detection-based Stokes-vector receivers and their basic configurations. Next, we describe three optical modulation schemes based on Stokes-vector direct detection, namely, the dual-polarization (DP) pulse-amplitude-modulation (PAM) scheme, quadrature-amplitude-modulation (QAM) scheme, and state-of-polarization (SOP) modulation scheme having the cubic-lattice constellation, together with their mutual-information characteristics. Using computer simulations, we compare the receiver sensitivity of these modulation formats. Especially, the effect of the branching loss of the Stokes-vector receiver is examined in detail. When we use the circuit-noise-limited receiver, the multi-level SOP modulation with the cubic-lattice constellation can compensate for the reduction of the receiver sensitivity due to the branching loss and has the highest receiver sensitivity per bit. On the other hand, when the signal is pre-amplified with an erbium-doped fiber amplifier (EDFA), the receiver sensitivity is not affected by the branching loss; therefore, the DP-PAM format has the best receiver sensitivity per bit. |
