| Outline of Final Research Achievements |
In this study, we investigated space division multiplexing technology for extremely enhancing optical transmission capacity by using multicore fiber technology and mode division multiplexing technology. For multicore fiber design, a theory for accurately estimating inter-core crosstalk in few-mode multicore fibers has been developed. Through detailed numerical simulations, it was found that the few-mode multicore fibers with a spatial multiplicity of 20 times larger than that of conventional single-core single-mode fibers can be achieved. In addition, for realizing mode division multiplexing, a planar lightwave circuit (PLC) based LP11 mode rotator was proposed in order to excite LP11b mode in the same plane, and the PLC-type 2LP-mode (3 mode) multiplexer/demultiplexer with uniform waveguide height has been developed.
