Metasurface-enabled non-orthogonal four-output polarization splitter for non-redundant full-Stokes imaging

Autor: Soma, Go, Komatsu, Kento, Ren, Chun, Nakano, Yoshiaki, Tanemura, Takuo

Imaging polarimetry plays an essential role in various fields since it imparts rich information that cannot be obtained through mere intensity and spectral measurements. To retrieve full Stokes parameters, at least four sensor pixels are required, ea

Complete vectorial optical mode converter using multi-layer metasurface

Autor: Soma, Go, Komatsu, Kento, Nakano, Yoshiaki, Tanemura, Takuo

A vectorial optical mode converter that can transform an orthogonal set of multiple input vector beams into another orthogonal set of vector beams is attractive for a wide range of applications in optics and photonics. While multi-plane light convers

Publikováno v: Optica 2023

The polarimetric self-coherent system using a direct-detection-based Stokes-vector receiver (SVR) is a promising technology to meet both the cost and capacity requirements of the short-reach optical interconnects. However, conventional SVRs require a

Scalable and Robust Photonic Integrated Unitary Converter

Autor: Tanomura, Ryota, Tang, Rui, Umezaki, Toshikazu, Soma, Go, Tanemura, Takuo, Nakano, Yoshiaki

Publikováno v: Physical Review Applied 2022

Optical unitary converter (OUC) that can convert a set of N mutually orthogonal optical modes into another set of arbitrary N orthogonal modes is expected to be the key device in diverse applications, including the optical communication, deep learnin
