Abstract: We theoretically investigate the effects of frequency
detuning and injection power on the nonlinear dynamics of DFB
lasers under dual external optical injection.
Abstract: We demonstrate a 40Gbps downstream PON
transmission based on PM-QPSK modulation using commercial DFB
lasers without optical amplifier in the ODN, obtaining 40dB power
budget. We discuss this solution within NG-PON2 architectures.
