An annular optical fiber with an asymmetrical optical grating and application in orbital angular momentum generation thereof

The invention provides an annular optical fiber with an asymmetrical optical grating and application in orbital angular momentum generation thereof. A hollow core annular optical fiber can increase the effective refractive index between degeneracy-similar modes, thereby preventing crosstalk between the modes. A long period optical grating inscribed on the upper half ring of the hollow core annular optical fiber breaks a circular symmetry structure of the optical fiber and achieves conversion between angular non-same order modes. When input light is of a circular polarization fundamental mode, a first-order orbital angular momentum mode can be generated. The hollow core of the hollow core annular optical fiber is filled with an optical functional material with the refractive index adjustable and the wave length for generating the orbital angular momentum mode can be tuned by the refractive index of the liquid, so that the structure can generate the orbital angular momentum mode in an adjustable cross band wave length range. Simulation shows that when the optical grating period is 292 [mu]m and the optical grating length is 1.460cm, the range of broad band wave lengths with the angular momentum mode conversion rate higher than 90% can reach 237nm, the greatest conversion rate is 98.91%, and the modulation rate of the refractive index of the filling liquid for the wave lengths for orbital angular momentum mode generation is 400nm/RIU.
