Traditional silicon-based electro optic modulators le mefokolo ea bona
Li-modulator tse entsoeng ka silicon-based photoelectric light e bile motheo oa mekhoa ea puisano ea optical ka lilemo tse ngata. Ho ipapisitsoe le phello ea ho hasana ha plasma, lisebelisoa tse joalo li entse tsoelo-pele e makatsang lilemong tse 25 tse fetileng, li eketsa litefiso tsa phetisetso ea data ka liodara tse tharo tsa boholo. Li-modulator tsa sejoale-joale tse thehiloeng ho silicon li ka fihlela 4-level pulse amplitude modulation (PAM4) ea ho fihla ho 224 Gb/s, esita le ho feta 300 Gb/s ka PAM8 modulation.
