| Abstract(in English) | Optical fiber devices utilizing periodical coupling between different modes of dissimilar optical fibers have been studied in conjunction with its application to optical communication, sensing and optical guided-wave electronics. For example, there have been proposed a mode converter, a mode filter, a frequency shifter, an optical narrow-band filter and so on. In this paper, a new taper-type optical fiber mode converter based on fused-tapered directional coupler has been fabricated by fusing and pulling together a pre-tapered and the original single-mode fibers which is well known as a thermally fused elongation method. The mode conversion between different propagating modes in a directional coupler made of dissimilar optical fibers is then analyzed by coupled mode theory(CMT) and will be computer-simulated with a beam propagation method(BPM). Comparison of experimental results with these numerical analyses allow us to efficiently design and fabricate a new taper-type optical fiber mode converter. |
