标题： Thermally tunable hybrid photonic architecture for nonlinear optical circuits

摘要： 我们开发了一种热可调的混合光子平台，包括砷化镓（GaAs）光子晶体腔、氮化硅（SiN$_x$）光栅耦合器和波导，以及在集成光子芯片上的铬（Cr）微加热器。 GaAs 光子晶体腔与一个公共总线波导进行倏逝连接，将计算层和通信层分开。 微加热器设计用于连续且可逆地将远距离光子晶体腔调整到共同的共振。 这种架构可以在相干光网络中实现，用于专用的光计算和机器学习。 显示英文摘要

摘要： We develop a thermally tunable hybrid photonic platform comprising gallium arsenide (GaAs) photonic crystal cavities, silicon nitride (SiN$_x$) grating couplers and waveguides, and chromium (Cr) microheaters on an integrated photonic chip. The GaAs photonic crystal cavities are evanescently connected to a common bus waveguide, separating the computation and communication layers. The microheaters are designed to continuously and reversibly tune distant photonic crystal cavities to a common resonance. This architecture can be implemented in a coherent optical network for dedicated optical computing and machine learning.
