By unifying ultra-high optical gain and broadband electro-optic dynamics in an Er-doped lithium niobate thin-film platform, the authors demonstrate an exciting monolithic integration of amplification and modulation on a compact photonic chip. This exciting work showcases record performance for on-chip amplifiers while enabling self-amplified 50 Gbps digital encoding and pre-amplified RF front-end signal recovery.
