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.

When an intruder attacks an object in an electric power network, it is necessary to successfully invade the target node along an attack path. However, as the number of target power optical network nodes increases gradually, the attack path will be exponential growth, resulting in path redundancy, affecting the overall performance of the generated path. To this end, a new power optical network attack path generation and visual display method, introduced the atomic attack, attack map and attack path definition. Based on the analysis of the cost and benefit of the attack path, the intrusion feasibility model is proposed, and the intruder’s choice of the attack path becomes the problem of the feasibility of the invasion. When the POS set contains all the directional edges of the power optical network attack map, generate the attack path of the power optical network by traversing the POS collection element. The process of generating the attack path of the electric power network is displayed. The experimental results show that there is no redundant phenomenon in the proposed method, and the generated attack path is effective and the reliability is high.
