About the Lecture:Ultra-weak grating is a novel optical passive device. It is a kind of spatial periodical refractive index distribution based on the photosensitive properties of optical fiber materials on the fiber core, and its function is to change or control the propagation behavior of light in the region. The appearance of the ultra-weak grating makes many complex optical fiber communication networks and sensor networks possible, greatly widening the application of optical fiber technology, and producing many important applications. Based on the theory of electromagnetic field, this report focuses on the fabrication technology, sensing mechanism, and the construction of sensor network, and introduces the application of weak grating in health monitoring of various environments.
