液芯长周期光栅
Liquid-Core Long Period GratingA fiber optic sensor structure consisting of a long periodic modulation of the refractive index in the core of an optical fiber, where the core is filled with a liquid. It operates based on the coupling of light between the core and cladding modes at specific wavelengths determined by the grating period and effective refractive indices. / 液芯长周期光栅是一种光纤传感器结构，由光纤芯中的长周期折射率调制组成，其中芯被液体填充。它基于在特定波长下芯模和包层模之间的光耦合进行工作，这些波长由光栅周期和有效折射率决定。
