Abstract

We propose and demonstrate an all-fiber Bessel beam generator based on M-type optical fiber and graded-index optical fiber. We show that the output optical beam from the graded-index optical fiber end-face is a Bessel-like beam, which is generated by Fourier transform of a ring light that is generated by M-type optical fiber using graded-index optical fiber lens. We also study wave propagation in this generator using beam propagation method. The simulated results show that the output beam from this generator is rather like an ideal Bessel-Gaussian beam.
