Abstract Space division multiplexing (SDM) is a promising optical network solution with the
scaling potential to overcome the possible capacity crunch problem in backbone networks …

Multicore fibers (MCFs) are one of the main technological enablers for space-division
multiplexing. In principle, MCFs could scale the fiber capacity by a factor equal to the …

To keep pace with the rapidly increasing network traffic demand anticipated in the coming
years, space-division multiplexing (SDM) has become a promising technology for …

Abstract Elastic Optical Networks (EONs) using a flexible wavelength allocation technique
with smaller granularity of spectrum can improve the efficiency and flexibility for diverse …

In this paper we focus on the efficient dynamic routing in spectrally-spatially flexible optical
networks (SS-FON). To this end, we propose novel adaptive spectral-spatial allocation …

In recent years, with the proliferation of emerging Internet services such as high-definition
video, online education, remote work, cloud computing, etc., network traffic is also growing …

Space division multiplexing elastic optical networks (SDM-EONs) are one of the most
promising network architectures that satisfy the rapidly growing traffic of the internet …

First, I would like to thank my advisor, professor Maiko Shigeno, for all her theoretical
support and guidance in completing the thesis. Her dedication and patience not only …

The application of optical transmission for the long-haul wired transmission system started
from the nineteen eighty. Compared to the electrical transmission system, the time-division …
