FIG. 2.

Energy distribution between the excited Bessel-like modes when light from SMF-28 is coupled into the core MM fiber. Inset part: calculated profiles of the SM fiber and selected Bessel-like modes inside the MM fiber.

FIG. 3.

Beam intensity profiles measured at selected distances from the fiber facet of the MM fiber for wavelengths of 1510 and 1570 nm, respectively, and their corresponding far-field intensity profiles. (a) , , (b) , , (c) , , (d) , , and (e) far-field patterns of (a)–(d).
