Article Synopsis
- A new orbital angular momentum (OAM) multiplexing apparatus has been developed to handle various topological charges using a method called multi-plane light conversion (MPLC) across four phase planes.
- The study focuses on the impact of fabrication errors, such as misalignment and etching inaccuracies, on the performance of the MPLC devices, with the goal of improving their production process.
- In a communication experiment, the device successfully multiplexed three OAM channels at a rate of 10 Gbit/s over 5 km of few-mode fiber, demonstrating strong performance with low bit error rates.
Objective: To present a bibliometric analysis of global scientific publications on the nondrug and nonsedative hypnotic treatment of insomnia with regard to influential institutions, publications, countries, research hotspots, trends, and frontiers.
Methods: A literature review was conducted by searching the Web of Science Core Collection (WoSCC) and China National Knowledge Infrastructure (CNKI) databases to identify all publications related to the nondrug and nonsedative hypnotic treatment of insomnia from 2000 to 2021. Eligible publications were reviewed, including annual publication increments, citation analyses, international collaborations, and keyword analyses.
Article Synopsis
- The combination of wavelength division multiplexing (WDM) and mode division multiplexing (MDM) can significantly boost optical communication capacity by using multiple wavelengths and modes simultaneously.* -
- Currently, there are no integrated parallel WDM devices designed specifically for wavelength-mode hybrid multiplexing.* -
- The proposed solution is a single 2 × 8 arrayed waveguide grating (AWG) that effectively multiplexes 2 linearly polarized modes over 4 wavelengths, with potential for future expansion to support more wavelengths and modes.*
Polarimetry has been demonstrated essential in various disciplines, such as optical communications, imaging, and astronomy. On-chip nanostructures for polarization measurements are most expected to replace the conventional bulk elements, and hence minimize the polarimeter for integrated applications. Some on-chip nanophotonic polarimeter via polarization detection has been implemented, in which the separation of two spin polarized states is needed.
