| Outline of Final Research Achievements |
Optical devices for mode-division-multiplexed (MDM) transmission are investigated. Scrambling-type mode multiplexers using silica-based planar lightwave circuit is proposed and 3-mode proof-of-concept device was successfully fabricated. For the compensation of mode dependent loss and differential group delay in the MDM system, 3-mode exchanger based on directional couplers is proposed and proof-of-concept device was successfully fabricated. Furthermore, to design mode controlling optical devices with large relative index difference, such as Si waveguides, full-vector wavefront matching method was successfully developed.
