Paper Abstract

We report here the fabrication of a single to dual mode evanescent field directional coupler for the first time. Experimental results are presented to show that such a coupler can be used to couple light into or to take out energy from the two modes of a two mode fiber (TMF) through a single-mode fiber (SMF). Such a coupler should be useful in the practical implementation of a two-mode fiber sensor making it compatible with the single mode fiber networks.
