摘要：

We investigate the use of optical differential phase-shift keying (DPSK) as the downstream modulation, format in a low-cost upstream data remodulation scheme for a Wavelength-division multiplexing (WDM)-based passive optical network. A 2.5 Gb/s upstream data transmitter is realized by directly modulating a Fabry-Perot (FP) laser, injection-locked with a 10-Gb/s downstream optical DPSK signal. A simple polarization-offset technique is proposed to largely minimize the induced power penalty.
