摘要：

An ultrahigh-speed modified uni-traveling carrier photodiode integrated on a thin-film lithium niobate platform has been proposed and fabricated. Experimental tests reveal a record-high bandwidth of 130 GHz with a responsivity of 0.35 A/W. This photodiode demonstrates high-quality detection of 50 Gbaud, 60 Gbaud, 80 Gbaud, and 100 Gbaud four-level pulse amplitude modulation signals in intensity modulation direct detection communication systems.
