Transverse Asymmetry of the Index Modulation Profile in Few-Mode Fiber Bragg Grating

open access: yesPhotonics, 2021
The transverse asymmetry of the index modulation profile in the asymmetric few-mode fiber Bragg grating (FM-FBG) was investigated. The transverse asymmetry of the index modulation profile will lead to mode conversion between modes with the different ...

A Few Mode Fiber Temperature Sensor Filled With PDMS Based on Vernier Effect

open access: yesIEEE Photonics Journal, 2021
A few mode fiber temperature sensor filled with PDMS based on vernier effect is proposed. It uses single mode fiber (SMF), few mode fiber (FMF), and polydimethylsiloxane (PDMS) to form the SMF-air microcavity-FMF-PDMS-FMF structure.

Few-mode-fiber technology fine-tunes losses of quantum communication systems

open access: yes, 2021
A natural choice for quantum communication is to use the relative phase between two paths of a single-photon for information encoding. This method was nevertheless quickly identified as impractical over long distances and thus a modification based on ...
