Abstract
We obtain an asymptotic expression for calculation of radiation fields of the waveguide modes of a multimode fiber with a step-like profile of the refractive index at high normalized frequencies. The distribution of intensity of the output radiation is calculated numerically. Statistical characteristics of the calculated speckles are found and compared with the experiment.
