Semiconductor Optical Amplifier Space Switch With Symmetrical Thin-Film Resistive Current Injection

Computational Model and Parameter Extraction of High Speed Semiconductor Optical Amplifier Space Switches

“…Furthermore, SOAs can perform optical packet switching, allowing the construction of SOA-based OPS (M × N switches), which can establish connections between ports in the order of few nanoseconds [28]. These devices take advantage of the polarization insensitivity [29] and ultrafast transitions from off to on operational states in SOA-based optical space switches [30], which is possible through the dynamic behavior of electrical and optical carriers in the SOA active region [31]]-[ [33]. In addition, SOA can simultaneously amplify the switched carrier, compensating for switch insertion loss and improving the optical link signal-to-noise ratio [34].…”

“…it is possible to adapt well known laser equivalent circuits [43] to simulate the SOA electro-optical response. This approach was extensively exploited in previously works [44], [45], [33], resulting in the extraction of approximate parameters from the characterized SOA. However, in those cases, the fitting between simulated equivalent circuit and experimentally evaluated responses was performed only on the frequency-domain, resulting in an inaccurate SOA behavior in time-domain simulations [44].…”

Improvements Evaluation of High-Speed Electro-Optical Integrated Thin-Film Microwave Coupler SOA-based Space Switch

“…SOA-based integrated modules are promising on the generation [10] and reception [11] of modulated optical signals. Furthermore, its versatility allows several electro-optical functions to be performed such as ultra-fast electro-optical space switching [12]- [14], WDM amplification [15], all-optical modulated signals regeneration [16], Improvements Evaluation of High-Speed Electro-Optical Integrated Thin-Film Microwave Coupler SOA-based Space Switch Tiago Sutili 1,* , Rafael C.

“…As presented in [12], the integration of microwave components decreases effects of microwave parasitics, significantly improving the switching performance. The present work aims to extend the discussion about performance, presenting a more in-depth analysis of the SOA-based switching behavior in several operational conditions and performing a comparative analysis between results of the microwave thin-film coupler mounting [12] and the ones achieved by the same SOA in a traditional microwave mounting.…”

“…METHODOLOGY The experimental results use the setup shown in Fig. 1, where the "SOA-based Switch" block refers to the microwave mounting proposed in [12] and detailed in Fig. 2, including the combination of the switching signals directly into the device mounting using a thin-film coupler.…”
