摘要

Ultraviolet (UV) light sensing is widely needed in many fields of human life and scientific research. All-fiber ultraviolet sensor based on the evanescent field including tapered fiber-optic interferometer and black phosphorous (BP) film is demonstrated. Understanding the UV-light-responsive composites is of great importance for UV sensor design. Here an alternative approach to observe UV photosensitive effect is discovered, which relies on tracing refractive index (RI) change of photoinduction performance by a silica microfiber interferometer. In this method, the light-induced RI variation of material is captured by the microfiber as the strong evanescent field interaction and it converted into wavelength shift in the interference fringes. The experimental results show that the time sensitivity of the BP-fiber waveguide sensor with dynamic response to UV light is 0.03 nm/min under 100 W illumination, and it also proves that there is a good linear response relationship between wavelength shift and different power UV light. The feasibility of optical fiber opens up a new approach for the fundamental research of UV sensor design, and the proposed sensor structure can serve as a platform for UV sensing in the future.
