论文摘要
我们展示了具有侧向P-I-N连接的硅光子微孔谐振器中的电压 - 可启动的热光稳定性和三稳定性，并提出了一种表征集成光谐振器的热光瞬态响应的技术。我们的热态瞬态响应测量方法适用于任何集成的光子平台，并使用标准设备。发现封装的波导中的热声弛豫在时间上近似对数，这与2D热扩散的分析溶液一致。我们开发了一个用于热电器多稳定性和动力学的模型，该模型与各种操作条件范围内的实验数据一致。我们的工作强调了在主动自由载体拆卸和热疗法加热之间的半导体波导中的基本连接，这是与Kerr Soliton状态稳定性和芯片频率梳子的产生特别相关的结果。这里研究的设备是在CMOS铸造过程中制造的，因此我们的模型可用于设计硅光子波导设备。
We demonstrate voltage-tunable thermo-optic bi- and tri-stability in silicon photonic microring resonators with lateral p-i-n junctions and present a technique for characterizing the thermo-optic transient response of integrated optical resonators. Our method for thermo-optic transient response measurement is applicable to any integrated photonics platform and uses standard equipment. Thermo-optic relaxation in encapsulated waveguides is found to be approximately logarithmic in time, consistent with the analytic solution for 2D heat diffusion. We develop a model for thermo-optic microring multi-stability and dynamics which agrees with experiment data over a wide range of operating conditions. Our work highlights the fundamental connection in semiconductor waveguides between active free-carrier removal and thermo-optic heating, a result of particular relevance to Kerr soliton state stability and on-chip frequency comb generation. The devices studied here were fabricated in a CMOS foundry process and as a result our model is useful for design of silicon photonic waveguide devices.
