Shandong Guangfang Software Technology Co., Ltd. was established in 2020 as a domestic enterprise dedicated to the research and development of independent optoelectronic simulation software. The company is headquartered in Jinan, Shandong, with a branch office in Wuhan, Hubei.

With a self-controllable technological approach, SimWorks provides secure, reliable, and efficient simulation tools for the domestic optoelectronics field. Based on algorithms such as FDTD (Finite-Difference Time-Domain), the company has independently developed the "SimWorks Finite Difference Solutions" optoelectronic simulation software, which includes three solvers—FDTD, FDFD, and FDE—capable of matching or surpassing international benchmarks in simulation accuracy and speed.

SimWorks adopts a cloud-native architecture, supporting cloud computing and multi-GPU parallel acceleration, significantly improving simulation efficiency and computational power. The software boasts comprehensive functionality and a user-friendly interface, making it widely applicable for the design of various optoelectronic devices and research in cutting-edge photonics. It serves as a vital tool for researchers exploring new theories and technologies.
