Fiber-Coupled Electro-Optic Phase Modulator

Sichuan Ziguan Photonics Technology Co., Ltd. was established in March 2015, located in Mianyang, the Science and Technology City of China. It is mainly engaged in the R&D, design, production, and sales of optical communication equipment and optical communication chips; it is a high-tech enterprise in optical communication with independent R&D capabilities and large-scale production capacity. Since its establishment, Ziguan Photonics has continuously invested in R&D and attracted technical talents in the communication industry. The company's projects are led by PhDs, with masters and bachelors collaborating in research and development. The company's products are increasingly diversified, including optical switches, optical attenuators, fiber delay lines, silicon-based optical chips, polarization controllers, MEMS optical switches, high-speed photodetectors, silicon-based high-speed devices, pulsed fiber lasers, femtosecond fiber lasers, semiconductor lasers, and optical path protection equipment (OXC). At the same time, the company also provides core high-precision optical components for lidar systems, quantum communication systems, laser fusion imaging transmission systems, etc. Among them, fiber delay lines, optical switches, and optical attenuators are mass-produced products with core technologies, and the product technologies have obtained multiple patent certifications, including 6 invention patents, and a total of 16 appearance, software copyright, and utility model patents. In 2024, the Xi'an Technology Center was established, focusing on three major fields: radio frequency, radar, and high-speed optoelectronic systems, dedicated to the industrialization of cutting-edge technologies. In the field of RF technology, it has full-chain capabilities from chip design to system integration. Its self-developed RF transceiver modules support ultra-wide frequency bands such as 0.1GHz~18GHz, and the innovative adaptive interference suppression algorithm can dynamically optimize signals to ensure communication stability in complex environments. In the field of radar technology, products cover industrial surveying (clearance radar), security (phased array), meteorology (wind measurement radar), etc., providing key data and early warning efficiency for wind power generation and regional security. Currently, it is exploring the integration of radar and AI, using machine learning to improve target recognition accuracy and response speed. In the field of high-speed optoelectronic systems, in response to the urgent demand for high-speed data transmission in scenarios such as data centers and supercomputing centers, we have developed high-speed acquisition card series, high-speed optical attenuation matrices, and other products, using silicon photonics technology to achieve low-loss, high-stability, and high-speed transmission, breaking through the bottleneck of traditional optoelectronic conversion. In 2026, the Wuhan Optoelectronics R&D Center was established, dedicated to breakthroughs in ultrafast and high-power laser technologies such as high-speed fiber lasers and femtosecond lasers, as well as the R&D and production of fiber amplifiers. In the same year, the Jiaxing Optical Chip R&D Center was established, focusing on the potential needs of future AI computing centers, drones, robots, medical equipment, microwave photonic radar, etc., specializing in the process R&D and manufacturing of silicon-based optical chips, ferroelectric crystal (thin-film lithium niobate, poled electro-optic polymer, PZT) modulation chips, III-V (GaAs/InP) chips, and subsequent chip packaging processes, consolidating the core chip foundation. The company has more than 150 customers and has established long-term stable strategic cooperation with well-known enterprises and institutions such as Huawei, AVIC, CETC, CAEP, universities, and aerospace. The company has successively obtained honorary titles such as "Technology-based Small and Medium-sized Enterprise", "National High-tech Enterprise", "Mianyang Civilized Youth", "2016 Honest Entrepreneurial Youth", "Military-Civilian Integration Enterprise", "2019 Outstanding Unit in Intellectual Property Work", etc. Sichuan Ziguan Photonics Technology Co., Ltd. adheres to the principle of technological innovation and has always integrated innovation into the core values of the enterprise. The company emphasizes a harmonious corporate innovation atmosphere and provides a broad development platform for every employee; in internal management, it attaches great importance to team spirit, promotes the development of the enterprise with the team's collective creativity, and is more systematic and professional, continuously providing customers with high-quality and comprehensive services, making Ziguan Optical Communication's products at the forefront of the industry.
