“…8). For this SOA design, a peak ASE at shorter wavelengths corresponds to lower PDG [20]. Interestingly, minimizing the cumulative PDG has the effect of shifting the peak ASE noise to the left, i.e., to a shorter wavelength.…”

“…6(a), the measured optical power of each of the three payload channels is plotted as a function of the number of nodes propagated for all three cases: High Gain, Low Gain, and No PDG. Preemphasis in the input power of the three payload channels compensates for the effect of the wavelength gain dependence of the SOA devices [20]. The average optical power is shown in Fig.…”

Abstract-The small polarization dependence (< 1 dB) of optical components becomes significant in optical multistage interconnection networks. The cumulative effect can ultimately limit physical layer scalability by changing the maximum number of internal nodes that optical packets can traverse error free. It is shown that for nodes based on commercial semiconductor optical amplifier (SOA) switches with polarization-dependent gains of less than 0.35 dB, the maximum number of cascaded nodes changes by as much as 20 nodes, depending on both the packet wavelength and its state of polarization. This deviation in the number of nodes could correspond to a 100-fold decrease in the number of interconnected ports of an optical interconnection network such as the data vortex. This dramatic effect is explained in terms of optical signal-to-noise ratio degradation due to accumulated amplified spontaneous emission noise originating from the SOA device in the node.Index Terms-Multistage interconnection networks (MINs), optical packet switching, polarization-sensitive devices, semiconductor optical amplifier (SOA).

“…The future high speed telecommunication systems are expected to use all-optical technologies to avoid optical-electrical-optical conversions. Semiconductor optical amplifiers can be used to perform a variety of all-optical functions, such as wavelength conversion, add-drop multiplexing (wavelength and time), regeneration, optical logic signal processing and switching [1]. They have the advantage of a compact size, high stability, a low switching energy, a high integration potential, and fast and strong nonlinearity characteristics [2].…”

“…Introduction: Semiconductor optical amplifiers (SOAs) have become a key technology for the development of lightwave communications and networks enabled by their ultra-wide bandwidth, low power consumption, compactness and ability for integration [1]. Nevertheless, in direct signal amplification applications the combination of the power and the duration of the input signal pulses can be such that the SOA is driven into intense saturation and cannot fully recover its gain until its next excitation.…”
