Abstract
Nowadays, forward Brillouin scattering in optical fibers has attracted massive research interests worldwide, owing to its great potential for applications in sensing, filtering, lasing, and all‐optical signal processing, etc. The manipulation of spectrum properties of forward stimulated Brillouin scattering (FSBS) turns out to be particularly important for various application scenarios. However, the manipulation approaches are still very limited by now. Herein, for the first time to the best of one's knowledge, a thorough investigation on the fiber geometry dependence of FSBS effect in optical fibers is presented, where the dependencies of FSBS on fiber core diameter and cladding diameter are investigated, revealing the characteristics of FSBS in terms of linewidth, frequency interval, and nonlinear coefficient, etc. It is indicated in the result that changing the size of the fiber core/cladding might give rise to considerable modification of the FSBS spectrum. The investigation paves the way to engineer FSBS in optical fibers, where acousto‐optic interaction can be manipulated and the FSBS spectrum can be tailored by adjusting the geometric size of the fiber for various applications.
