“…Now the wavelength converter reported can generally realize a single channel wavelength conversion, which is difficult for multi-channel wavelength conversion. Multi-wavelength converter [6], which has realized multi-channel wavelength conversion, reduces the cost of network expansion. Multi-wavelength conversion exploiting XGM in semiconductor laser has attracted intensive attentions owing to its simple structure and easily implemented.…”

ABSTRATWe proposed a simultaneous three-wavelength conversion based on the cross-gain modulation (XGM) in the multi-wavelength semiconductor fiber ring laser (SFRL). It is easily implemented owing to the simple structure.Furthermore, it has realized multi-channel wavelength conversion, which reduces the cost of network expansion. A comprehensive broadband dynamic model is presented. By numerical simulation, the proposed multi-wavelength conversion is theoretically realized using the broadband dynamic model. Moreover, the dependences of conversion efficiency and extinction ratio on the input signal power, signal wavelength and injection current are investigated in detail.

We demonstrate a novel all-optical half-adder based on two semiconductor optical amplifiers (SOAs) . Two optical bandpass filters are used to select the two idlers generated by four-wave mixing (FWM) effect of the first SOA. Therefore, the AND gate and XNOR logic are realized simultaneously. The second SOA acts as a NOT gate, in which the NOR logic is achieved with the input of the logic XNOR. As a result, the output is the sum of the two input bits and the carry. In the experiment, all-optical half-addition calculation is achieved between two 10 Gb/s signals.The all-optical logic operations of the all-optical signal processing become one of the key technologies in all-optical networks [1][2][3] . Semiconductor optical amplifier (SOA) has been widely investigated in the application of all-optical logic. The half-adder, as a basic combination logic unit, is the basis of full adder and counters. At present, several schemes on the all optical half-adder, including non-linear loop mirror [4,5] , terahertz optical demultiplexer (TOAD) [6] , cascaded SOA and PPLN [7] , are pruposed. The first two schemes have the disadvantage of instability, the cascated scheme is difficult for the integration.A novel scheme is proposed to achieve the all-optical halfadder based on two cascade SOAs in this paper. Based on the cross-gain modulation (XGM) and four-wave mixing (FWM) effect in the SOA, the AND gate and XNOR logic are achieved in the first SOA simultaneously, the NOT gate is realized in the second SOA, consequently the sum bit and carry bit of the all-optical half-adder are obtained, and successful operation of the system is demonstrated with 10-Gb/ s all-optical half-adder.A half-adder with a pair of input bits generates two corresponding output bits, and the relation between the carry bit (the logical AND function) and the sum bit (the logical XOR

“…Differential phase-shift keying (DPSK) format has attracted much attention recently because of its 3-dB benefit in receiving sensitivity and superior tolerance to fiber nonlinearities [7] . Many methods have been used to perform wavelength conversion of DPSK signals [8] , and a maximum conversion efficiency of 85% has been achieved by using FWM in highly nonlinear fiber (HNLF) [9] .…”

We numerically investigate the main constrains for high efficiency wavelength conversion of differential phase-shift keying (DPSK) signals based on four-wave mixing (FWM) in highly nonlinear fiber (HNLF). Using multi-tone pump phase modulation techniques, high efficiency wavelength conversion of DPSK signals is achieved with the stimulated Brillouin scattering (SBS) effects effectively suppressed. Our analysis shows that there is a compromise between conversion efficiency and converted idler degradation. By optimizing the pump phase modulation configuration, the converted DPSK idler's degradation can be dramatically decreased through balancing SBS suppression and pump phase modulation degradation. Our simulation results also show that these multi-tone pump phase modulation techniques are more appropriate for the future high bit rate systems.
