“…5 are for a bias current of 400 mA, but when the conversion efficiency is increased by increasing the bias current, the effective carrier lifetime decreases [12]. This results in the increase in NLPN [9], thereby resulting in a trade off between the FWM conversion efficiency and NLPN [9].…”

“…5, it can be inferred that the variance of NLPN is inversely related to the carrier lifetime and directly proportional to the linewidth enhancement factor [9]. The conversion efficiency of FWM process is inversely related to carrier life time [12]. Hence, when the carrier life time is reduced to increase the FWM conversion efficiency, it increases the NLPN.…”

The impact of nonlinear phase noise on all-optical wavelength conversion using four-wave mixing and dual-correlated pumps is studied. It is shown that there are optical signal-to-noise ratio requirements on the dual-correlated pumps for penalty-free all-optical wavelength conversion. We also show that the nonlinear phase noise generated in the nonlinear medium is transferred to the idler because of the uncorrelated nature of the amplitude noise on the pump signals.Index Terms-Four-wave mixing, wavelength conversion, nonlinear phase noise.

“…For the wavelength conversion of the QPSK signal data, the generated optical QPSK signal is then coupled with two pumps (one SGDBR laser and one narrow linewidth ECL) and sent into the SOA-based wavelength converter. For both QPSK and PM-QPSK schemes, the power of the signal and the pumps at the input of the SOA are set at −10 dBm and 0 dBm, respectively, for optimum conversion efficiency [48]. The signal wavelength undergoes wavelength conversion through non-degenerate FWM in the SOA operating at 500 mA bias current.…”

Abstract:We theoretically analyze the phase noise transfer issue between the pump and the wavelength-converted idler for a nondegenerate four-wave mixing (FWM) scheme, as well as study the vector theory in nonlinear semiconductor optical amplifiers (SOAs), in order to design a polarization-insensitive wavelength conversion system employing dual co-polarized pumps. A tunable sampled grating distributed Bragg reflector (SG-DBR) pump laser has been utilized to enable fast wavelength conversion in the sub-microsecond timescale. By using the detailed characterization of the SGDBR laser, we discuss the phase noise performance of the SGDBR laser. Finally, we present a reconfigurable SOA-based all-optical wavelength converter using the fast switching SGDBR tunable laser as one of the pump sources and experimentally study the wavelength conversion of the single polarization quadrature phase shift keying (QPSK) and polarization multiplexed (Pol-Mux) QPSK signals at 12.5-Gbaud. A wide tuning range (>10 nm) and less than 50 ns and 160 ns reconfiguration time have been achieved for the wavelength conversion system for QPSK and PM-QPSK signals, respectively. The performance under the switching environment after the required reconfiguration time is the same as the static case when the wavelengths are fixed.

“…Considering the case with ASE noise, We ignore the amplification of spontaneous emission in SOA and replace |E| 2 in (5) with |E| 2 + P AS E , where P AS E is the total ASE power. Then the modified gain equation can be obtained (Baveja et al 2012)…”

Aiming at the characteristics of distributed satellites system that the information exchanging and wavelength conversion are frequent but the payload is limited, a wavelength conversion scheme based on the self-phase modulation (SPM) and the four-wave mixing (FWM) is put forward, which can substitute several pump lasers in case of multiple wavelength channels. By utilizing the SPM in high nonlinear fiber to broaden the spectrum of initial signal, a pre-conversion signal is obtained as the pump light for wavelength conversion through an offset filtering. Then the wavelength conversion is realized based on the FWM in semiconductor optical amplifier. The principle of the scheme is deduced theoretically, and the relationship between conversion properties and structural parameters is analyzed. The simulation results show that the scheme can improve the quality of signal to some extent when completing a wavelength conversion, the Q factor improvement can be of 3 dB at most, while the conversion efficiency can reach to 20 dB.
