| Abstract(in English) | Multimode (MM) optical fibers can transmit high energy and can be easily used for connection and splicing because of its large core diameter. However, due to microbending-induced mode coupling the multimode fibers exhibit a speckle pattern at the output of the MM fiber. In this paper, single-mode excitation of step-index and graded-index multimode fibers with light sources with short temporal coherence lengths is demonstrated using a Ti : sapphire laser with wavelength the of 790 nm and 836 nm and pulse widths of 60 ～ 90 fs. The mode-coupling coefficients and launching efficiencies are determined experimentally from diffraction half-angle of the output pattern exiting from the MM fiber and single-mode (SM) excitation in the presence of mode-coupling is discussed for the MM fibers. |
