Design of an intelligent electromagnetic simulation system for high-frequency circuits based on the optoelectronic coupling effect

Accurate description of optoelectronic coupling effects in high-frequency circuit simulation is crucial for enhancing simulation precision. This paper proposes a deep learning-based electromagnetic simulation method for optoelectronic coupling, establishing an improved carrier transport model. Through a time-domain/spectral-domain hybrid algorithm, it achieves precise solutions for both optoelectronic coupling effects and electromagnetic fields. An end-to-end intelligent simulation platform is constructed, enabling automatic extraction of optoelectronic characteristics and rapid prediction of electromagnetic fields. The research outcomes provide novel technical solutions for optimizing the design of high-frequency optoelectronic devices and circuits, holding significant implications for enhancing the simulation accuracy of optoelectronic integrated circuits.
