Established on September 1, 2023, Photonvite Intelligent Technology (Changzhou) Co., Ltd. ("Photonvite Tech") is a national high-tech SME anchored in Jiangsu's intelligent sensing industrial ecosystem. Founded in Longhutang Street, Xinbei District by a France-returned Ph.D. (recipient of Jiangsu's "Double Innovation Talent" award) alongside an elite R&D team from China's top 985 universities, the company has pioneered breakthrough innovations in industrial sensing technology. Within two years, Photonvite Tech has successfully filled critical gaps in domestic silicon photonics sensing, establishing new industry benchmarks.

MOMS (Micro Opto-Mechanical Sensing) silicon optical sensor chip uses a silicon-based F-P (Fabry-Pérot) micro-nano optical interference cavity as the sensitive structure, and uses optical fiber as the carrier for signal detection and reading. MOMS silicon optical sensor chips adopt semiconductor processing technology, which mainly involves process steps such as lithography, coating, etching, deep etching, bonding and dicing; the chip size is micro-nano, can be manufactured in batches, and has good consistency.

The sensitive element made of MOMS silicon optical chips overcomes the problem of mutual constraints between high sensitivity and wide dynamic range, and has characteristics such as low thermal noise density, high resolution, wide temperature, and wide frequency. The encapsulated MOMS silicon optical sensor mainly has the advantages of passive detection, electromagnetic immunity, long transmission distance, wide operating temperature, wide frequency response, and high precision. It can work well in harsh and dangerous environments and provide accurate signals. Silicon optical sensing systems can serve industries including rail transit, battery cells, nuclear energy, coal mining, transmission, aviation and aerospace, helping customers accurately detect trace changes in physical quantities, and ultimately helping enterprises achieve real-time monitoring and intelligent operation and maintenance throughout the year.
