摘要

提出了一种基于Er3 +掺杂铌酸锂薄膜（Er: TFLN）的光波导的片上放大自发发射（ASE）源。该集成器件在C+L波段实现了9.16 mW的宽带输出功率，相对于吸收泵浦功率的斜率效率为4.7%。该器件具有低传播损耗、大模场和单模传播的特点，可通过光刻辅助化学机械蚀刻技术实现。

Chip‐Based Amplified Spontaneous Emission Source on Er3+‐Doped Thin Film Lithium Niobate

An on‐chip amplified spontaneous emission (ASE) source from an optical waveguide fabricated on Er3⁺‐doped thin‐film lithium niobate (Er: TFLN), is presented. The integrated device achieves a broadband output power of 9.16 mW spanning the C+L band, corresponding to a slope efficiency of 4.7% relative to the absorbed pump power. The device features low propagation loss, large mode field, and single‐mode propagation enabled by the photolithography assisted chemo‐mechanic etch technique.
