Design of a Trench-Assisted Optical Fiber for Generating Bessel Beams With Different Shapes
We have designed a trench-assisted optical fiber that can generate Bessel beams with different shapes in the fundamental mode. The trench-assisted structure is nested by rings with different refractive indexes on the cross-section. The fundamental mode field properties of the trench-assisted fiber a...
