Publikováno v: Optical Fiber Communication Conference (OFC) 2023.

A single multicore-fiber bidirectional spatial channel network that efficiently accommodates asymmetric traffic is proposed and demonstrated using a core-selective-switch-based spatial cross-connect with an M × N wavelength-selective switch and a bi

Core Selective Switch Supporting 15 Cores Per Port Using Bundled Three 5-Core Fibers

Autor: Yudai Uchida, Tsubasa Ishikawa, Itsuki Urashima, Shoma Murao, Takahiro Kodama, Yasuki Sakurai, Ryuichi Sugizaki, Masahiko Jinno

Publikováno v: Optical Fiber Communication Conference (OFC) 2022.

We prototyped a 15-core 1×8 core selective switch (CSS). The high core count CSS is achieved by bundling three 5-core fibers (5-CFs) and collimating/demultiplexing beams from the input bundled three 5-CFs using a single microlens.

Experimental Demonstration of Ultrawide Bandwidth-Range Optical Channel Provisioning Using SDM/WDM Hierarchical Optical Cross-Connect

Autor: Tsubasa Ishikawa, Yudai Uchida, Takahiro Kodama, Masahiko Jinno, Itsuki Urashima

Publikováno v: OSA Advanced Photonics Congress 2021.

We show ultrawide-bandwidth-range (100 Gb/s to 38.4 Tb/s) optical channel provisioning in a spatial channel network testbed using a hierarchical optical cross-connect demonstrator based on newly developed core selective switches.

Ultra-Wideband and Low-Loss Core Selective Switch Employing Two-Dimensionally Arranged MEMS Mirrors

Autor: Masahiko Jinno, Tsubasa Ishikawa, Takahiro Kodama, Itsuki Urashima

Publikováno v: OFC

We experimentally show an ultra-wideband (130 nm), compact (~50 mm), low insertion loss (< 2.7 dB), and low-polarization-dependent-loss (< 0.25 dB) five-core 1×8 core selective switch employing a two-dimensionally arranged MEMS array.
