Comb mode converters based on sampled helical gratings
Yancheng Ma, Liang Fang, Guoan Wu
Helical gratings (HGs) have an achievement of flexible mode conversion for fibre guided orbital angular momentum (OAM) modes. Sampled reflection HGs can realise the generation and…
Analysis of the bandwidth of resonant spectra for tilted fiber grating
Liang Fang, Hongzhi Jia
Based on coupled mode equations, the formula of null null bandwidth for tilted fiber grating is deduced in this paper. Numerical simulations and theoretical analysis of the effects…
Generation of cylindrically symmetric modes and orbitalangular momentum modes with tilted optical gratings inscribed in high numerical aperture fibers
Liang Fang, Hongzhi Jia, Hai Zhou +1
Optical fiber with high numerical aperture (NA) can efficiently relieve the degeneracy of higher order linearly polarized modes. The degeneracy relief is investigated in two types…
Fiber guided mode analyses and conversion using superposed helical gratings
Yancheng Ma, Liang Fang, Guoan Wu
Optical fibers can support various modal forms, including vector modes, linear polarization (LP) modes, and orbital angular momentum (OAM) modes, etc. The modal correlation among t…
