Ultra-high-linearity integrated lithium niobate electro-optic modulators
文献摘要:
Integrated lithium niobate(LN)photonics is a promising platform for future chip-scale microwave photonics systems owing to its unique electro-optic properties,low optical loss,and excellent scalability.A key enabler for such systems is a highly linear electro-optic modulator that could faithfully convert analog electrical signals into optical signals.In this work,we demonstrate a monolithic integrated LN modulator with an ultra-high spurious-free dynamic range(SFDR)of 120.04 dB·Hz4/5 at 1 GHz,using a ring-assisted Mach-Zehnder interferometer configuration.The excellent synergy between the intrinsically linear electro-optic response of LN and an opti-mized linearization strategy allows us to fullly suppress the cubic terms of third-order intermodulation distortions(IMD3)without active feedback controls,leading to~20 dB improvement over previous results in the thin-film LN platform.Our ultra-high-linearity LN modulators could become a core building block for future large-scale functional microwave photonic integrated circuits by further integration with other high-performance compo-nents like low-loss delay lines,tunable filters,and phase shifters available on the LN platform.
