“…The SOA dynamic response calibration was performed following the technique proposed in [47] and detailed in Section C. Through this approach, it was possible to precisely tune the SOA static optical gain in the VPI environment [42] as a function of its bias current and optical input power. This first SOA response approximation was then expanded considering its dynamic behavior when switching pulses, as the ones evaluated in Section A via Simulink environment [41], were summed up with the device bias current, as discussed in Section D.…”

“…Usually, length and width can be measured using scanning electron microscopy on an open device, and length can be obtained by analysing residual Fabry-Perot modes [48]. However, these parameters, among several others, as showed in Table 2, can be obtained through heuristic extraction, employing numerical analysis, as presented in [47]. This approach was experimentally implemented by using the setup presented in Fig.…”

“…Next, the parameters listed in Table 2 were individually tuned from its default values, analysing the impact of their variation on the simulated curves of optical gain versus bias current and versus input optical power. 'Default' are values preconfigured for a standard SOA in the VPI software and that were used as start profile for the calibration technique presented in [47]. The SOA active region's optical confinement factor, width and thickness are parameters of greater interest and impact on the overall static behavior and, then, firstly analysed.…”

A characterization technique, including a mathematical model involving extensive computational resources, is introduced to study the behavior of an electro-optical space switch based on semiconductor optical amplifier (SOA). The model encompasses the precise emulation of device nonlinearities and its transient performance, allowing the characterization of its transient response. The calibration process includes the evaluation of parasites from the SOA connection, mounting and encapsulation, and parameter extraction of the active cavity. The numerical results are compared to experimental data for various operational conditions, with close similarities. The characterization technique can be adapted for other electro-optical devices, such as directedmodulated lasers, amplitude modulators and electro-optical switches.

“…Vagionas et al [15] presented experimentally validated SOA numerical modeling techniques applicable to a wide range of SOA devices by using the transfer matrix method (TMM). In [16], they reported an optimized SOA model using the transmission line matrix (TLM) method to simulate light propagation through the active region of SOA. Shawki et al described a theoretical model of the SOA time domain oscillation dynamics, used for the simulation of the oscillation dynamics in the SOA-based random laser [17].…”

The role of a semiconductor optical amplifier (SOA) for amplifying downstream traffic at optical network terminals (ONT) within a silicon-photonics integrated receiver in a high capacity passive optical network (PON) is investigated. The nearly traveling wave SOA effects are evaluated by considering fabrication and link loss constraints through numerical analysis and experimental validation. The impact of hybrid integration of a SOA chip on a silicon on insulator (SOI) photonic chip using the flip chip bonding technique on SOA design is evaluated through numerical analysis of a multi section cavity model. The performance of the proposed ONT receiver design employing twin parallel SOAs is evaluated experimentally on a 32 × 25 Gb/s OOK WDM transmission system considering cross gain modulation (XGM) and amplified spontaneous emission (ASE) constraints. The XGM impact is evaluated through 32 channel wavelength division multiplexing (WDM) transmission and a likely PON worst case scenario of high channel power difference (~10 dB) between adjacent channels. The impact of ASE is evaluated through the worst-case polarization condition, i.e., when all of the signal is coupled to only one. Successful transmission was achieved in both worst-case conditions with limited impact on performance. SOA results indicate that a maximum residual facet reflectivity of 4 × 10−4 for the chip-bonded device can lead to a power penalty below 2 dB in a polarization-diversity twin SOAs receiver.

“…Those parasitics reduce the SOA effective electrooptical bandwidth and induce electrical oscillations on the switching control signals. Previous works [22], [23], mainly based on the SOA electrical equivalent circuit modeling, showed the encapsulation impact on the overall device performance, highlighting the fundamental importance of a careful and optimized microwave mounting to avoid unwanted reflections and oscillations on the electro-optical switching process.…”

The speed and transient improvements due to a thinfilm microwave coupler on a high-speed SOA-based space switch are analyzed. The switch performance is compared with another one using the same SOA device but in its commercial butterfly encapsulated form factor. Through an extensive experimental characterization and an automated algorithm analysis, the switching actions were evaluated in several SOA operational conditions (bias current, electrical pulse step amplitude, preimpulse amplitude, and switching technique) employing metrics related to the switching times and transient behavior intensity. The results showed that the thin-film coupler SOA switch mounting led to switching time improvements and quicker optical output pulse stabilization. In conjunction with the appropriated switching technique, the device could achieve switching speeds around 200 ps aiming its operation in high-speed optical networks.
