With the full advent of the "AI4Science" era, massive data processing and complex model training have posed unprecedented challenges to foundational computing power. Traditional silicon-based electronic chips are gradually approaching the physical limits of Moore's Law and are constrained by the energy efficiency bottleneck of the Von Neumann architecture. Optoelectronic integrated chips, with their advantages in high bandwidth, low latency, and low power consumption, are recognized as the key breakthrough for the next leap in computational power. However, due to the optical diffraction limit, conventional photonic devices are significantly larger in size compared to electronic devices, making their "size mismatch" on the nanoscale a critical obstacle to high-density optoelectronic integration. This report focuses on polariton materials, which are regarded as promising foundational materials for next-generation optoelectronic integration. We have successfully designed a wide range of functional devices, spanning from the excitation and modulation of polaritons to their detection. This research establishes a solid foundation for the efficient integration of future optoelectronic systems.
