    Optical fiber integrated devices have attracted increasing attention due to its advantages of small size, and high-degree integration of diverse functionalities. Traditional fiber integrated devices are usually composed of dielectric or metallic microstructures, which rely on expensive and complex lithography process. Moreover, the functionality of fiber optics with static and fixed geometry is unadjustable, which greatly limits their applications. In this article, we design and demonstrate an optical fiber end-facet integrated liquid crystal (LC) photonic devices for beam shaping. The LC polymer droplets with planar and homeotropic anchoring on the single-mode fiber end-facet were prepared to realize the beam shaping devices in the visible. These two kind of LC polymer droplets with special director configurations were simulated using Q-tensor model and Rayleigh-Sommerfeld diffraction theory. The optical properties of the LC polymer droplets under different anchoring conditions were experimentally verified. The experimental results match the simulation results, thus proving the beam shaping ability of the LC devices. This study provides a new approach to realize compact and integrated optical fiber optics with lower cost and high efficiency.
