Abstract

To enhance the portability and stability of the thin-film lithium niobate modulator (TFLNM) under different working conditions, an integrated bias controller is proposed and demonstrated based on multi-physics simulation modeling algorithms and heterogeneous integration strategies. A new transmission formula with higher accuracy is enabled according to the integrated device. Theoretical analysis results show the fabricated devices have a bandwidth over 110 GHz. Experimental results show the device can operate stably for 3500 hours online at 110 GHz, with mere 0.01°C phase point drift. Notably, the Transmitter and Dispersion Eye Closure for PAM4 (TDECQ) achieves 1.91 dB. To our knowledge, this is currently the best-performance electro-optic hybrid integrated TFLNM, which is suitable for large-scale network calculation.

集成偏压控制器的铌酸锂薄膜调制器的演示

为了提高薄膜铌酸锂调制器（TFLNM）在不同工作条件下的可移植性和稳定性，提出了一种基于多物理场仿真建模算法和异构集成策略的集成偏置控制器。根据集成装置，实现了精度更高的新传动公式。理论分析结果表明，所制器件的带宽超过110 GHz。实验结果表明，该器件可在110 GHz频段稳定在线工作3500小时，相点漂移仅为0.01℃。值得注意的是，PAM4的发射机和色散闭眼（TDECQ）达到1.91 dB。据我们所知，这是目前性能最好的电光混合集成TFLNM，适用于大规模网络计算。
