Multiple quantum-well (MQW) electroabsorptive self electro optic-effect devices (SEEDs) are being extensively studied for use in optical switching and computing. The self electro-optic-effect devices which has quantum-well structures is a new optoelectronic technology with capability to obtain both optical inputs and outputs for Gallium-Arsenide/Aluminum Gallium-Arsenide (GaAs/AlGaAs)... https://jalyttlers.shop/product-category/stopper/
