Abstract: Embodiments of the invention include an optical energy transmission system and apparatus having improved mode coupling. According to embodiments of the invention, an optical energy transmission medium such as an optical fiber (10) includes a plurality of particles (26) formed in one or more coating region layers (17,18) surrounding the cladding region (14) and/or one or more buffer region layers (23,24) surrounding the coating region for inducing microbending thereof, thus promoting advantageous mode coupling, which improves bandwidth potential by reducing dispersion. The method for manufacturing the inventive optical energy transmission medium includes forming one or more coating region layers and/or one or more buffer region layers containing particles such as fumed silica in such a way that particles are maintained within the optical energy transmission medium and form controlled perturbations along the optical fiber that enhance mode coupling to the extent that bandwidth of the optical fiber is improved.
