In this paper,a novel all-solid anti-resonant single crystal fiber(AR-SCF)with high refractive index tubes cladding is proposed.By producing the cladding tubes with high refractive index material,the AR guiding mechanism can be realized for the SCF,which can reduce the mode number to achieve single-mode or few-mode transmission.The influences of dif-ferent materials and structures on the confinement loss and effective guided mode number for wavelengths of 2-3μm are investigated.Then,the optimal AR-SCF structures for different wavelengths are determined.Furthermore,the influences of different fabrication errors are analyzed.This work would provide insight to new opportunities in the novel design of SCFs by AR,which would greatly impact the fields of laser application,supercontinum generation,and SCF sensors. 展开更多
