Abstract.  We present a large-core single-mode “windmill” single crystal sapphire optical fiber (SCSF) design, which exhibits single-mode operation by stripping off the higher-order modes (HOMs) while maintaining the fundamental mode. The “windmill” SCSF design was analyzed using the finite element analysis method, in which all the HOMs are leaky. The numerical simulation results show single-mode operation in the spectral range from 0.4 to 2  μm in the windmill SCSF, with an effective core diameter as large as 14  μm. Such fiber is expected to improve the performance of many of the current sapphire fiber optic sensor structures.
